this all the way. high school classes, no matter what, are not hard. people were all like, "oh, AP chem was hard but i still did it." AP chem was shit and taught almost nothing and was just a ton of work. go into school as a chem major and you'll see. inb4 college chem compared to high school chem is unfair, thats exactly the point i'm making.
that aside all those kids with straight A's in hard classes that can't actually do anything with their knowledge are going to do bad on SAT's. application is everything.
