SAT non-native speaker

I’m going to take the SAT this coming nov. 7 for the first time! i bought the famous blue book and tried 1 section and got 1370 (CR:440 M:510 W:420) i’m aiming for 1600-1700 although 1800 would be the best, and i want to ace it until next month! i know its impossible but i’m willing to put all my effort into it. here is my main problems…

  1. always OUT OF TIME. for critical reading and writing, i always end up missing 5-8 questions. as for math i always miss 2-4 questions.
  2. I’m really weak at math section. i don’t understand the meaning of the question sometimes, and it confuse me wether i should use arithmetic formula or algebra formula! any advice to raise my math score? i heard that memorizing the formulas and understanding the question will enhance my score…
  3. Critical Reading is very very very hard for me. I have to read the passage like twice or trice to understand the passage fully. Also, the vocabulary is super hard for me. any tips…?
    Prep Books i have:
    :black_circle:︎SAT official study guide
    :black_circle:︎Barrons sat writing workbook
    :black_circle:︎Barrons sat math workbook (currently not using, because it’s too hard)
    :black_circle:︎Hot words for the Sat
    :black_circle:︎Sat unofficial word dictionary
    I’m also thinking of buying Grubers for Math and Black book for strategies…
