SOS! ACT/SAT , HELP!!!

I am an international student
can you please suggest the books and all the stuff how to prepare for these exams?

See the pinned SAT books thread under “SAT Preparation.”

There are a lot of tips and tricks around preparing for both exams, which you can find with a search through past CC threads.

For the ACT, Barron’s 36 is really good for English. I studied from Barron’s and got a 35 in English. It explains grammar rules really clearly and I found it useful in general. For math, Princeton Review and Barron’s 36 are good. Also make use of online resources

I didn’t find anything for science and reading…
thank you though!

thank you very much!
