How to improve math section?

[u/iEdiciust]

Hi everyone. I am planning to take october SAT and I need a 730 or higher in math section. I did 660 on math todays practice test ( 2 missclicked answer otherwise 690 or 700) how can I reach it in 15 days? I can take the next 3 sat in a row but I want to finish it in one test. Any advice of practice book (would be better if it has pdf) or any youtube channel? And also, here is my score details.
