For the UCs and top colleges like cornell and johns hopkins, is it better to not submit my ap chem test score at all, or just show it to colleges even though i got a 2?
Do you want to go into a science major? If yes, then include it.
I personally wouldn’t, even if you are going into a science major. I’m sure people have gotten in with lower AP marks, but it really doesn’t benefit you in any way to display it.
