Was always a 6/10 in hs, never had to really study anything because 120IQ in third world educational system. Now a 21 yo husk of my former self and got into a top federal public uni in chemicl enggineering, which is something i am interested but i am grinding my gears hard because i forgot much of the little i saw in HS. Please help. I want to learn how to study STEM w/o forgetting everything, the gits of higher ed, if i can catchup with hs math, chem and phisics while in uni.
