SAT Critical Reading, TIPS? Options

[Relentless]

So I have SAT 1 (Again!) on March 1st (THAT'S LIKE A WEEK LEFT FROM TODAY!). I was not satisfied with my first one in December 1st. I noticed that Critical Reading pretty much is the worst score ever.

There is quite some big words and there are words that I have seen before but I don't know what it means or I don't even say/write it. I tried studying some big words on my Barron's PREP book, but not sure if it will give me a good score on my second try. (I'm deciding to take it the 3rd time)

I have a Barron's SAT Prep book, which I have been doing since my 1st SAT.

I already know that a lot of people been saying like just read more books, study the vocabs in prep book, but of course I know that. I just want to know if there are any other extensive ways to improve it.

Tips anyone to improve Critical Reading score?
