HOW DO I INCREASE MY READING SCORE IN 3 MONTHS?

Hi everyone! So I am currently a Junior and I will be taking the SAT in May and possibly be reaking it in June. I want to get the SAT out the way before the summer to prep for Subject SATS. Basically I have about 3 months and I am currently scoring in the 1850-1950 range.
When I take practice tests my :
math scores are 720+
writing scores are 680+
reading scores are 500.
I am struggling greatly in Reading and for some reason I can not raise my score. I am trying to get a 2150+. Is it possible to get this score in just 3 months? What is the fastest way and best way to get a reading score of 650. I heard Direct Hits is really good and I am currently memorizing a bunch of word lists. Is Direct Hits something I should buy? Are there any other books that are good for boosting up my reading score? Or should I keep on doing College Board? Also any tips for reading passages I would greatly appreciate. Thank you.

In CR if you are missing Vocab questions, DH or other word lists will help but you still got to learn to tackle the passage based questions. It will take a lot of practice and use the pinned thread in this forum to try some of those out and see which one best suits you. They include reading questions first or looking at questions and marking out line numbers or reading passages first or a combination of different things. If you are looking for a book, I hear (from this forum) about Erica Meltzers Critical Reading book.
