In the SAT test, how many breaks are there?
If you are only taking one or two Subject Tests, you may leave the test center after your final test is finished. # You may work on only one test during each testing hour. You will get a short break at the end of each hour of testing time. # You can take up to three Subject Tests on one test date. # You can change your mind on test day about which Subject Test you want to take. You may substitute a Subject Test (other than a listening test), or add Subject Tests (other than a listening test) on test day. i got how to to information and preparation details in http://exam-study.
