When I went into college I thought everyone had just finished precalc and was going into Calc 1. Nope. Literally half the freshman went into algebra as their first college math class. I know it’s only gotten worse. A huge portion of high-school graduates not going to college can’t do trig, they can’t do long division, they can’t even multiply two 2 digit numbers. I just saw a tik tok about people trying to do 51*51 and the majority couldn’t.
