SAT Subject Tests vs. AP

Hi CC Readers!

Right now I am in AP Chemistry and AP US History and I have been able to maintain As all year. We are beginning to prepare for the AP exams in these classes.

Anyways, I signed up for the SAT Subject Tests in these fields. I was wondering if preparation for the AP Exams knocks out two birds with one stone. Is the material on the Subject Tests the same as the AP? Are the formats the same?

Thanks so much!

No. The APs are 3 hour exams with a combination of multiple choice and free response questions. The Subject Tests are one hour exams that are MC only.

For history, yes, IMO. For chem, no. The Subject Test covers more breadth.
