What kind of practice test should I use to improve my SAT score?

Test Preparation
1

I already finished 10 tests from the Blue book and 8 SAT official test from online. I improved my SAT score by 600 points but I still want to improve 300 points more. Are official PSAT test helpful to practice for SAT? What are the best SAT books in market beside college board book? And I only have a month to prepare (taking the old SAT in January).
Thanks

That’s a ton of studying.

PSATs are useful prep. You can try tests written by test prep companies. There may be additional actual tests that some CC users have that were never officially released. You’d really have to dig for those.
