Gohan doesn't lack experience in battles, by 11 he surpassed his father and became, at that time, the strongest in the universe as buu was still dead or locked away and he even took on buu as well becoming the strongest unfused character in dbz as ultimate gohan. Also at 6 he went up against frieza, who was at the time undeniably strong, his name was enough to completely scare king kai and owned a galactic planet control organisation. At the time of the namek saga, nobody, not even vegeta would dare go up against him but yet he fought him took him down, before frieza went into his stronger form. Taking on cell, frieza and buu, being the strongest in the universe twice, ultimate gohan and super saiyan 2 gohan, I think that qualifies as the highest level of experience in the universe, even if in between cell and buu, he started to slack off a bit.
