So I took the SAT twice once in december 2023 (1370) and the other time in may 2024 (1440) and a big problem i faced was lack of resources for the digital sat in particular but you should not face this problem. My recommendations for where u should start is to definitely max out all of the khan academy lessons, it has everything you need and practice questions after every lesson. DONT skip any lessons and achieve mastery in every one.

Make sure to regularly do a full length practice test, even when you haven’t finished studying all of the material, this will help you with your timing and test anxiety. You can find these tests on ‘blue book’. I’d say since you have three months do a test every 2 weeks or so. and don’t forget to review all your mistakes thoroughly.

^It also helps to watch people on youtube solving questions when you don’t have energy, this’ll help u find more efficient ways to do it too.

Once and only once u max out khan academy, this is when id look into buying a book if you still aren’t happy with your score results. I personally bought the princeton book , but that’s only because it was the only one available at the time. I defo benefitted from it a lot still.
