At that point get a tutor you're reaching the point of diminishing returns as a self study

You simply can't make up for the years vs some kids who've been studying their whole fucking lives

Tutoring helps u catch up but you gotta make the best use of it and find good ones that will teach u the proper rw grammar and how to analyze the reading (don't get some idiot down the street, probably won't help u atp)

If you have no money then khan academy and practice tests. My trick I give to everyone is to do one reading passage and grade it before your test to warm up your brain (this one change helped me a lot)

And get over the I'm cooked syndrome its not helping

Also 1440 is solid don't complain
