If you have problems with basic math skills, it doesn’t matter how many practice SAT questions you do—you’re going to have to fix those knowlege gaps before you can improve your SAT Math score.
If you notice you’re missing practice SAT Math questions because you are uncomfortable in a certain content area, work on your content weaknesses before you do anything else.
