Any ways to increase my critical reading score to above a 700 in 2 months?

So SAT scores just got released today and I got a 2190
Writing-760
Math-800
Critical Reading-630

I’ve been trying to improve my critical reading score for the past year and the only change I’ve seen is a 100 point jump from the 500s into the 600s. I’m definitely retaking in January but I have no idea why my score won’t improve. I usually miss alot of questions in reading comprehension and not so much in the Vocab.

How many sentcoms do you miss?
