SAT problem plz help

i have couples of questions , from what book should i study for Biology , Chemistry & M1 ? i dont know many informations in these 3 subjects please help

Biology: Princeton Review or Barron’s. PR preferable.
Chemistry: Kaplan or Princeton Review. Either of them are okay.

Can’t say anything about M1.

with Prinston / baron’s review you mean the book?

Yes, the book.

M1 is Princeton.
Chem: Try Barron’s as well.

I’d suggest you avoid Barron’s for Chemistry, unless you have a very long time before the exam. Like, a really long time.
