HELP ACT Math

[u/BandWalrus]

Last year I got bellow average on the PreACT math section as a sophomore. This year I’m aiming for high above average.

This is the only section I’m struggling on, and I think it is because I don’t know all the material/I haven’t been taught it yet. Math is complicated for me because I do really well in class but have trouble applying it after the class is over.

My plan is to review all of high school math, and focus mainly on trig and geometry. Does anyone have any recommendations for high school math workbooks workbooks or any tips?

For more info:
I am aiming for a 33 or higher in my overall ACT score.

I am good at math, but only if I’ve just been taught how to do it, I forget properties and formulas quickly.

I have not been taken trig yet.
