How to study from now on to increase up to 2200s...

I’ve got my score just now and it is not what I have anticipated…
Math 770
Critical Reading 600
Writing 620 ( Essay 9)
Total 1990

And I am genuinely concerned because there are only about 3 months left until the last SAT before the new one
I have devoted so much time on CR/WR since this May and I did a lot of tutors, camps, and stuffs like that.
I DO NOT KNOW HOW SHOULD I STUDY FROM NOW ON TO INCREASE MY SCORE…

Can anybody give me a piece of advice?
I have a books of:
-Barron’s SAT
-Barron’s writing workbook
-Barron’s Critical reading workbook
-Barron’s SAT 2400
-Collegeboard Blue book (1 already solved/2 void)
-Princeton review 11 practice tests for the SAT

and how is the “black book” and “shawn patel’s 7 steps to 2400?”
I am planning to buy those books…

I am pretty desperate here… It would be very thankful if you give any kind of advice…

I have no idea how to study for vocab. I think I’ve mastered pretty essential ones and I’ve encountered bunch of “i-have-never-seen-this-before” words in the real test.
