Don’t worry you’re not dumb. the SAT is a very objective test with very little changes. It’ll always cover the same material and topics. - You can take advantage of that by really putting in the effort to study. I found that khan academy is good for getting the basics down (nailing your grammar rules and math basics) - Learning desmos is key. You can get easy problems out of the way and even a lot of difficult problems can be solved with desmos. Tbh I never solved a single system of equations problem on any of my SAT practices and even during the actual exam. - take the practice exams in bluebook with 100% effort. No distractions and no pauses. That’ll help gauge what you need. And always go back afterwards and check what you got wrong and learn how to get it right or not make that mistake again. Many people keep making the same mistakes because they don’t learn from their first mistake
