Good at math, but suck at SAT Math (the hard questions)?

I’m pretty good at math–straight A’s,etc. at school–but I’m really bad on the questions labeled as"hard" on the SAT

on my 10th grade PSAT I got something like this on the math section:
easy; 10 out of 10
medium: 18 out of 18
Hard: 3 out of 18

I ALWAYS miss the hard questions–and I think to correct that I need to find a good way to prep

I tried Grubers b/c it has been heavily recommended on these boards, but Grubers did not help at all

Any suggestions on how to prep for the hard math questions?
