What/how to study for just math for PSAT the day before?

Overall, I do decently on the reading and writing but utterly bomb the math section, mostly because the math tested is stuff I did in 8th and 9th grade and calculus isn’t tested on the PSAT. So, what can I do to get a good overall review for the majority of math concepts without staying up all night researching every type of PSAT question possible? Also, does anyone have a list of equations/formulas that one should know? Thanks a ton everyone.

Note: No, you are not hurting your chances for NM by helping me, as I have no chance, I just want to have thhe highest possible score I can get so I know what I need to focus on for the SAT next year.
