THE HARDEST SAT Math Problems

22nd session Tue Mar 31, 2026, 2:00 PM

I prepared 18 pages of all the SAT Math problems with the lowest accuracies. I studied this list for the December SAT and earned an 800 on Math on my first try. I want to share the problems and go over them one by one! Let us all achieve a full score.

I really like how the problems actually covered real questions ive seen on the tests before (I didn't solve some of them, sadly). Thank you for going over them patiently and giving tips for checking answer! The tip is so inspiring!

Thank you for the machine learning Q&A. I was quite nervous at the beginning but soon your friendly attitude helped me relaxed. I will read all the materials you provided during this session (they are really helpful so far). Hopefully you will have time to hold another Q&A session for me.
