So I got a 1430 on both of my SAT’s. I will be taking it again and would like to know what is the best way to study to get over a 1500
take a lot of practice tests. I improved my verbal score by 70 points by doing that, because I began to see patterns in how questions were posed, etc. Practice tests also help for math but less so in my opinion. I think you will do best in math by being confident with the material (I would recommend diagknowstics online platform to brush up on that stuff and do extra practice).
That is a great SAT score! Don’t spend too much time stressing about raising it a lot. Do a bunch of practices, take it again, and be happy knowing you will be a competitive applicant at almost all schools (for reference it is equivalent to a 32 ACT). Great job!
