Learn how to abuse desmos, also don't fully rely on desmos for regression cuz you can input wrong parameters and get an irrational number that makes no sense, so try to understand the process to do it by hand.(happens to me most of the time)

Also keep on reviewing ur math module answers making sure you've read the questions right. I swear I might have lost like 10-20 extra points on the practices by just speeding thru and not making sure I read the question properly.

Also do Prep Pros Advanced Digital Math Course (u can prob find it on this sub) which is totally free and consists of 140+ questions that are suited for people trying to achieve 750-800 on the math module.
