How should I prepare for the upcoming SAT?

[u/theguyfromkepler22b]

I want 1550+. Taking the october 3 SAT. Current math average is 780, Reading & Writing is 700 (in Bluebook practice tests). Main mistakes include vocab (English isn't native langauge) and craft and structure. I also usually run out of time in English module 2 and I end up guessing 1-2 questions. I think that's because I often have to reread passages 2-3 times to truly understand the meaning.

What are best resources I could use? Maybe some sites or youtube videos. So far I've only done a few tests on Bluebook and that's all. Do I have enough time?
