PSAT Prep in a month??

Im a junior and started studying for the SAT a couple weeks ago, but I never improved much. I got my score to a 1300 more or less. The PSAT is coming up in a little over a month, and so far what ive done is take two practice tests from the blue book. What can I do in this next month to get the best PSAT score possible?

I would also like help with prepping for the PSAT. I made a 1370ish/208 NMSC score on a practice PSAT in the Barron’s PSAT 1520 book and I have to raise it to 220 since I live in Texas. :frowning:
