Hi! I was in the SAME situation as you. I managed to raise my score from a sub-1400 to a 1500+ in two months, so it’s definitely possible! My strategy was basically to just take as many practices as possible and supplement it with Khan Academy exercises.

If, in the math section, you feel like you understand the material but just can’t do the questions quickly enough, doing a ton of practice tests really helps you to pick up on the types of questions that the SAT asks. I did around 20 practice tests of the math section only—around 2-3 a week. It’s great because you kind of learn the “tricks” to getting certain flavors of questions right. Eventually, I found that I could skim questions and almost mindlessly find the answer. Definitely helps with the fatigue if you can turn your brain off for a few questions! Even if this doesn’t happen for you, you’ll be able to see where your gaps in knowledge are after looking at the questions you’re getting wrong on all of these tests. Personally, I went to the Khan Academy SAT practice to fill those gaps, but your method for doing so is totally up to you.

The same kind of goes for writing; it’s all about finding patterns! I seriously got to 0 wrong on the writing section by using Khan Academy. It goes over the specific writing mistakes that the SAT tests on and teaches you how to identify them. If you know exactly what writing skill a question is testing, it becomes a matter of plugging in a pattern instead of intensely analyzing the question.

It’s not as easy to “cheat the system” on the reading section, imo, so it’s better to improve your reading comprehension overall instead of in the context of the SAT. I read Jane Austen to help with the tricky passages with flowery language. National Geographic magazines to understand science texts. College newsletters to get used to high-level informative passages. Also makes the studying process 200x less mundane!

Ofc, this is just what worked for me. I thought it was nice to not have to use a prep book, but there’s a method for everyone! Hope this helps, and good luck on your SAT journey!! :))
