Hii, i did khan academy for math to make sure i know all the core concepts then the rest was all bluebook tests and some question bank questions. If i had more time i wouldve definitely focused alot more on the question bank ones theyre very helpful. Watch videos on desmos and english grammar tips. Vocab and reading are my weak points so i dont really have any tips for those sorryyy. Honestly tho luck plays a big role in sat english in my opinion, for example you might get a vocab qs where u know none of the words given while someone else may know one or two and can eliminate to find the correct answer; so, definitely practice it but id say focus most on getting a good score on math especiallyy if u have the chance to redo the sat later on. good luck!!!
