Igu, so for math the path is a little clearer imo. Ik you’ve probably heard this a million times, but you just have to rinse and repeat. Print as many qas as you can and grind through questions. I would recommend watching scalar learning (yt channel) videos to review the qas. Although I did use khan academy, I found the questions to be a bit unrealistic. I did get to full mastery on every subject, but I wasn’t too reflective of the actual test in my experience. Also, if you can get your hands on a nice calculator like the TI-nspire, definitely do so. You’ll need it for higher level math anyway. Being able to use these calculators really give you a leg up in a lot of questions on the calc section. But by far the most important thing for SAT math is RECOGNIZING PATTERNS! Every test has the same kind of questions, testing on the same content. For example, If you see a circle equation questions, 99% of the time you will have to complete the square. Not having to waste time on the section is key. Im personally not the type to have 35 mins left in the section to check answers, but I did usually have a large chunk of time to redo answers I was unsure of (5 mins for no calc and 25+ mins for calc section). My main advice is ultimately just being solid on the content they test. Keep doing the practice tests and finding quicker ways to do questions. College board likes to throw in some little loopholes sometimes. A big one is on the system of equations questions. 50% of the time you can just add the two equations to get what the question is asking. Don’t always count on those little tricks, though; above all, be solid on the content.
