So I took my SAT the first time in March. I was a 10th grade international student (I studied by taking 5-7 practice tests) and I scored a 1520 (780 EBRW, 740 Math). I've registered again for the SAT in September, and I'm targeting a 1580 (I know a lot of people say it doesn't make that much of a difference, but as an international Asian student, I do need to increase my math scores to be at par with others from my demographic + I've just started the 11th grade so I do have time to take it again).
How do you suggest I study? I'm extremely busy with school and extracurriculars, so I want a quick + cheap study method that doesn't involve sitting down for full length tests. I've tried Khan academy but it didn't work that well for me as I found it a bit overwhelming. Thanks!
PS: The first time I took it, I had time left and reviewed each section multiple times, so it came down to me just not knowing the answers. I think I need more help with content than time management.
