Crash Course in Math?!?

I’ve never done too well on the PSAT ( as a junior, the last one I took was 1050). But, I thought with studying I’d be fine for the SAT. I got lazy. I’m taking the exam on March 11. I got lazy because I was enrolled in a course which I guess I assumed would magically hack my score into test brilliance?!? I almost never have the answers when the others do in my SAT Kaplan course and the practice test I took, especially in the math department, was WAY worse that the 600 I got on the PSAT. I’m in panic mode because I 'm realizing that I don’t remember the majority of the math now that I’m done with Algebra and am in Trig.

Please, if you know any YouTube’s that can quickly teach math or study tips. Let me know! Now, that I know I’m in hot water, I WILL study my ass off and once I set on studying, especially youtube videos, I can potentially conquer. This YouTube strategy has really worked for my studying for the AP Euro exam and my chem final, so hopefully it will transfer to math even though math is super hard for me?

Or any other sites that help with SAT math in specifics.

Right now, I am doing the Kaplan hw and Khan academy which seemingly have different problems in that Kaplan is way more word problem based? It feels like no improvement is happening which I do think is partially because even if there’s an explanation at the end of the book, it’s not the same as a teacher going through the problem?

Oh boy, I’m already banking on having to take the SAT again, but good luck to both me and anyone else taking the exam!
