Top 10 Most Difficult School Subjects

As if school isn't hard enough, this list shows which subjects are the hardest!
The Top Ten
1 Physics

For the majority of people, physics is very tough because it is applying numbers to concepts that can be very abstract. Electricity and Magnetism is just one example that can be taught during the first year. For me, physics is actually quite simple and it is very interesting when you fully understand it and its applications. If you fundamentally understand what is happening, sure equations are nice but you understand why the equation works, making it much easier to memorize instead of just guessing which equation to use. But for me Foreign Languages are the hardest to learn just because I could never take the time to learn another one. They say the best way to learn is to go to another country though.

I consider myself to be pretty good at math and science. I did great in calculus, biology, and chemistry, however physics was a different story. After taking it in high school I swore I would never put myself through it again, but after deciding to major in chemical engineering I took it once again in college. I thought I might understand it better the second time having already taken it a couple years prior. I didn't. Physics is just one of those subjects where you either get it or you don't. You have to be able to understand how to properly apply the equations you learn. There isn't really a set equation for any type of problem. Physics is a subject more about applying your knowledge rather than memorizing a bunch of information.

2 Chemistry

I'm a high school student from Hong Kong, taking the HKDSE curriculum. In my Hong Kong it is without a doubt that chemistry is the hardest elective to take in high school, as it's a combination of hard concepts like math, calculations and forces like physics and loads of memorisations like biology. Chemistry students are just built different.

Science was actually my favorite subject as a kid. I always looked forward to going to my science class in middle school, for it was my best class. As a current freshman in high school, taking Chemistry Honors, I can now say that science is by far my least favorite subject. I have nothing against science, I simply don't like learning it. Here's why I find this subject difficult:

Chemistry isn't science on its own. Chemistry is actually a mixture of science and math. Now this doesn't really bother me because math isn't hard. However, it is one of the reasons why I find this subject difficult. Normally when you think of science you answer questions based off your own personal knowledge mixed with factual evidence you get from lessons and textbooks. With chemistry that sort of goes away. Because we bring math into the equation, questions in Chemistry will actually require you to think and work out the problem. Questions can differ greatly because of the different possible ways it can be asked due to the infinite amount of numbers we have.

Chemistry has a disgusting amount of reasoning, rules, laws, statements, definitions, equations, etc. This isn't a big problem if you're memorization skills are on point. This unfortunately means if you aren't really smart but still manage to get straight A's, like me, you will struggle in this class. It doesn't matter if you pass with an A+, somehow in one way or another, you will struggle in this class. The problem with chemistry is that everything you learn is essential to one another. In other words, everything you learn in chemistry is important. You can't learn one thing without knowing the other. This is where all those reasoning, rules, laws, etc. really bite you in the ass. Because there are simply just too much things to learn, it makes chemistry a really difficult subject.

Chemistry will require a lot, and I mean a lot, of positive attitude, effort, time, and determination to pass the class. Unless... more

3 Foreign Language

I took French for all 4 years and it really didn't get bad until the 4th. Honestly the worst part about a foreign language is all the different tenses and genders and forms of words. It's so confusing. Other than that basic vocabulary isn't hard, and it ends up getting easy to read sentences and know what the words mean even if you have never seen them before. My French 4 in 12th grade was a college level course, so it ended up getting hard, especially since everyone in the class was smarter than I was. The worst part about my experience with French was that I started with such high hopes and excitement, and left with an immense disliking for the language.

I was in fourth grade when I learned Japanese, it was my favourite subject and I loved learning a new language. We had two Japanese teachers who would award us with prizes whenever I answer a question correctly. They were so nice and friendly and honestly better than my actual teacher who teaches Math and English. But when I moved to another Primary School, I learned Italian which was easy but boring because I didn't express any interest with the language due to the simplicity it presents. When I was in High School, I did Japanese until eight grade because I failed a test where I need to learn another dialect of Japanese.

4 Math

Quite literally the only subject I'm "failing" (A-, but it still really bothers me). The hardest part is that I don't hate math. I actually quite enjoy solving equations and word problems. I'm just so bad at it! I can't think logically and the numbers seem to float aimlessly in my head. I struggle in this class and I clearly won't be going into a mathematical profession. Rather than embarrassing me in class because I can't answer something that seems basic to everyone else, just teach me what I need to know for life. Sure, every job requires math, but basic math and easily calculated math. It's not practical to keep shoving numbers where they don't need to be.

I find Math really difficult because to me, numbers have never really been my strong suit. Numbers cause my head to spin and it becomes very difficult to think through. I mean, I have never denied that it was important, but it just is so incredibly difficult to work with them. It's so easy to make mistakes and Math is usually the one that hinders one's ability to score well. And I don't like that is is about right or wrong. I prefer things like English and Science because those subjects are subjective and they actually teach us something useful. AA lot we learn in Math I never use, because seriously? Do we need to learn algebra?

5 Calculus

Just saying but, all subjects are easy as long as you're interested in it. Even calculus can be easy, as long as you are interested in what you read, it's easy to understand the topic. In my elementary years, I was never really that... interested in being an honor student. I've used to think Science and Math is hard. I thought the honor students had this special technique on studying which makes them smart. So I forced myself to study topics that, I didn't really understand. I forced myself to gulp in all the words in the textbooks, but my grades got lower instead of higher. I just, gave up and studied the way I would study. In my highschool years, I got interested in Math. I didn't notice but, my grades were getting higher. Not long after, I was an honor student. Sometimes, you just have to be interested in what you read. Even average students can lap honor students. as long as you have a goal set by heart and mind, everything else will turn out as how you expected it to turn out.

6 English

English belongs in a trash can. Recently, I started to read an article about a TedTalk. I keep on practicing until the test. During the test, I just forgot to add one apostrophe and one full stop and my grades drop down fast. It's either my teacher doesn't really like me, or you just need to make your sentence fully perfect. Those advanced English words seem really rare and no one ever said those words before. English requires a lot of thinking and need to try your best to become successful at English. I feel like when people said that not everything in life is perfect, I feel like this is a myth. I'm a normal English person who likes to practice. Practicing math is the easiest thing to do. Math is my favourite subject and should be.

English Is the most annoying subject ever. My teacher and my marker would always say there is a problem. "I don't like this vocal", "It is too wordy", "State the answer", "why are you not expanding on it", and "The reason why you got 12/15 is that you did not add the apostrophe and the sentence it not clear". No matter how hard I try or how long I practice, I can't get 100%. The highest I ever got from my school experience was 87%. The rest of the time, I got 70% and 60% and I've been a student over 10 years. You could never please the teacher or the marker.

7 Biology

Biology is by far the most fundamentally useful subject of all the sciences. Being able to understand the logistics of life yields a more appreciative perspective on life. A through foundation of the complexity of life requires hard work though. Taking university courses in chemistry, physics and maths, I can say that biology required the most work to study. I enjoyed studying it the most as it was the most relevant to direct life. Learning about titrations and yields in chemistry, calculus and statistics in math and equations that explain motion in physics.. ALL are relevant but not to the point of biology. I can walk outside and understand every organism and see the beauty in what it holds. I invite any naysayers to look through a microscope at a wet elodea cell and tell me that cytoplasmic streaming isn't awe inspiring...tldr biology is the most work to understand but it's the most rewarding.

8 Trigonometry

So frustrating. If you don't understand something completely, your done for. The sad thing is: you either get it or you don't. In order to ace a test you must have near complete mastery over what you have been taught. Countless times I've taken an exam believing that I would do well, but in the end receiving a terrible score. You must be excellent at math to do well in this subject.

I agree. Trigonometry is so hard. At least with the other math subjects they are built on things you have learned in the past. With Trigonometry, there is about one day of review, and everything else is new. I had straight-As in college before taking this subject. It was a good thing I dropped the class, but now, I have a W (Withdrawal/Fail) on my college transcript.

This is one of those classes where you have to really understand it to do good. If you memorize the equations, and spend hours studying them and their applications, chances are you will still get a D on the upcoming test because you couldn't apply them to the questions your teacher prepared.

9 History

I just don't like learning history. You need to do a lot of memorization and all that stuff about a random dude who did something. Yeah you can know about him but it should not be a main subject, you know what I mean?

HARDEST CLASS I'VE EVER TAKEN. Of course each person is different, but I would believe for this to be the hardest subject for me. No doubt it gets pretty interesting, but I simply SUCK at memorization and I feel this subject relies heavily on memorizing dates, events, and having natural skill at understanding DBQs (Document Based Question) and SAQs (Short Answer Question) and writing LEQs (Long Essay Question). Obviously, the skills can be strengthened, but they aren't always natural for everyone.

I wish History courses would be replaced with life skills and personal finance. Heres how it should work:
World or US history (for future college students)
World Economics
US economics
Personal finance

Those are classes we will use. Students should have a basic understanding of history, the doomed to repeat if you don't learn from the past thing is true. But 1 or 2 courses are all we need. Current events, economics, and personal finance are skills we need.

10 Computer Science

I am currently taking AP Computer Science A in 11th grade, and it is so hard and stressful. My mom forced me to take it. I am not interested in coding and I don't want to be a programmer or go into a computer science or engineering field when I grow up. I literally can't even remember the basics of coding and I have to get help from my mom for every assignment. It's worse because I am stupid and a slow learner compared to my peers, and I have no motivation for anything in general. I also do terribly on tests, especially on questions when we have to write the code for the question. I have like a B+ in the class. I would be getting a C-D or even failing the class if my mom didn't help. My motivation is getting even worse because I have 2 more weeks and 4 days before summer starts, and I am just tired of school in general. I can't wait for this terrible school year to end. After that, I literally don't want to do anything related to programming again.

The Contenders
11 Algebra

I had to take Algebra in 7th grade because of a 6th grade placement test, and let me just say that it is not the easiest thing in the world! Try going from the simplistic 6th grade math, where the only "algebra" you were doing were incredibly simple equations with just one or two variables, to much harder equations that included negative numbers, multiple variables on both sides of the equation, and much more complex formulas that you had to learn! It made no sense to me at first, until I finally understood the weird rules as to how everything all works. Now I passed the final exam with flying colors and am hoping Geometry in 8th grade will go a lot smoother for me.

Ok so in the 8th grade, I was put in an Algebra 1 Honors Class. Lemme just say it was one of the hardest classes I have every took. the first three chapters are easy (equations, Linear and Slope) then chapter 4 comes with Scatter Plots and awful Graphing. Chapter 5 is Easy (Inequalities). chapter 6-11 is all nearly impossible. We only spent around 3 weeks on each chapter so it was a very fast paced class. It gets downright impossible to keep up with Quadratics and radicals where you really need time to get good at doing. Overall, if you spend the time - Algebra isn't hard but if you don't understand things Easy - you are screwed.

12 Engineering

Took intro to engineering and the due dates were short, what made it hard is that the teacher talks way too fast and even though you ask question, you still wouldn't get it. You also have to use mathematics In this class and in my opinion I think it's rough.

I haven't taken engineering yet, but I'm planning to if I have time among the other subjects.

All subject in engineering particularly in physical science is hard

13 Algebra II

This is the hardest subject I have come across, I'm in 9th grade in the top class in my grade for math even though I passed last year with a C. I asked my 8th grade math teacher why he thought I met the standards for the class, and he said I scored well on the state testing. Really. What the heck is with state testing? I think it should be removed. Anyway, I have a B in this class and for the first marking period I had a C, not a good grade. Looking back, Algebra 1 was rather easy. This is just complete nonsense.

I'm sitting here with a C in this class. You either get it or you don't and I'm part of the latter. This is the first class I've really struggled in ever and it's really bringing down my self confidence. My motivation is low as well because I just can't bring myself to see the point in all this.

And I thought algebra 1 was hard. I just recently started to understand how to plot a graph and realized that the x axis comes before the y axis, yet here I am getting bombarded with complex algebraic equations that always confuse me as to which operation I'm supposed to use as it changes almost every time.

14 Geometry

This class made me feel like a complete numpty. My self-esteem levels went from extremely high to extremely low. I'm writing this a year later and I forget everything about Geometry. Algebra is much easier in my opinion. Then again, my school made me take the same course I took in 8th grade that I already passed solely because I went to a public school and they were a private school. Yes, proofs were VERY vexatious if you could not remember every single step to why your answer was correct. Here's a few valid points to back up my claim about Geometry:
-I found SOHCAHTOA the most complicated.
-Even my friend dreaded Geometry on the same level that I did.
-I barely had enough time in my schedule to get tutored by my school. It came to the point where I stopped paying attention and got the same grades that I did when I was paying attention.
To conclude my point, I believe Geometry is by far one of the hardest high school subjects because it just never made much sense to me. I don't think it is useful for every single career unless you want to be an architect or something along those lines.

15 Science

For some reason, I've lacked the skills for science even though I read a lot in things like social studies but science is kinda different for me due to the fact the teacher doesn't do that many discussions but instead notes and textbooks for us to memorize. I know some people might find this much better and easier for them, but even though I'm not really the type of person to be too social, discussions are just different from just memorizing off of notes or textbooks. This could also be due to my teacher's teaching methods which is something I can not change, but it still doesn't change my opinion that I find science different because of not only the topic but also the fact that in order to learn we only take notes and read the textbook.

Science is false. Religion is much less complicated and more simple and accurate. Evolution and critical race theory should be removed from the curriculum and replaced with intelligent design.

16 Integrated Math

Whoever thought this was a good idea and that anyone would do well in this class was clearly smoking something. The students hate it, and nobody does well in it.

This subject made Calculus look like it's for kiddies.

17 Organic Chemistry

It's all of the problems you had in regular chemistry, but now the difficulty is 3x harder and filled with unneeded complications.

It's so hard to find sources to support your statements when writing an essay.

Hardest class I ever took. Honorable mentions: Microbiology, Architecture and Biochemistry

18 Statistics

Stats is more of a logic course than a math course.

With formulas, try to forget the symbols/letters/etc and try to understand exactly what you're doing in each step.

Statistics is so harder then other subjects...which person only have this subject he/she knows that how difficult it is...I am a 12th class student of science and I have is more difficult then normal math...only top class math students plzzz follow this subject otherwise let it go...

Why isn't this higher? I struggled in this class!

19 Mandarin

Okay, so when I went to a private school, we had to learn Mandarin. Writing, speaking and reading it. After six months of going to a local, normal school I have forgotten 99% of what I learnt.

For sure. I used to know how to write in Mandarin, but after 1 year with no lessons, I have forgotten almost everything. It's really hard to remember. So many little lines!

World's toughest language!

20 Philosophy

In school I failed Philosophy with the lowest grade allowed in my school... 05E... My teacher told me she didn't give me a lower grade cause she wasnt allowed to...

It's quite easy and interesting learning about other people's views.

I hate school

21 Latin

Latin is a little hard. I have a 100 in it, but all you need to do is pay attention. In first quarter I never listened and got mostly c's d's and f's. But then I listened and got a 93 to end the quarter. But I would much rather take Spanish than Latin.

Learn french, spanish, italian. As simple as that although I don't know latin.

There! That is the rule of changing a English word into a Latin word!

22 Metaphysics

With consistently little to basis in reality, almost totally abstract, metaphysics is extremely difficult in that you can not just memorize or go by a formula, you really have to think, other subjects are similar to your brain going for a jog as metaphysics is powerlifting, you are really forced to THINK when given such broad concepts as being, knowing, reality, etc.

23 Accounting

You never know what is going on in this module, If you miss one part the everything is gone. Since all topics are integrated.

It's easy in the begining then it gets complicated. Everything needs to be understood because one may get lost. Then you'll have to cope with timing issues. Tough

Accountancy is the second hard subject after physics dude!

24 Arabic

The Arabic language is so beautiful and meaningful. If you try and you know some vocabulary and extend the answer, It will be so easy. Reading Arabic books can help learn new vocabs and structure of sentences

If this was taught in English schools, I would say one thing: LEL! And that's for no reason. Spanish, French and English are my limits.

Average years to learn this language is 9!
Making it the most difficult language worldwide.

25 Computer Programming

Computers do not operate like humans and are extremely dumb. As a result, you need to give them copious amounts of information so programs will execute. This setback, combined with heavy amounts of logic and remembering how different methods work make programming very challenging. Got a D- in Java initially (despite attending class), but got a B+ the second time.

This is the hardest and most confusing class I've ever had so far. I'm a 'grandma' when it comes to computers so I honestly don't know what I was thinking when taking the class. I'm so lost with the language the coding language, it's unbelievable.

I am a senior in highschool. I have a 4.2 weighted gpa, and I have been talking a lot of honors and AP classes. And by far computer programming was the hardest class I have ever took in my life. DO NOT take this class if you are not experienced with programming!
