Will taking the SAT subject tests conflict with the SAT reasoning tests?
The SAT subject tests are given at the same time and locations as the SAT reasoning tests, except in March when only the reasoning test is offered. Every time you take a subject test, you give up the chance to take the reasoning test. As noted above the optimal time to take the subject tests are in May and June during the school year when you are taking the course related to the subject test. If you plan to take the SAT reasoning the test, you should try to take it at a date that does not conflict with the optimal times to take the subject tests. As an alternative, you should consider taking the ACT instead of the SAT reasoning test since the dates never conflict with the subject tests. The ACT is accepted by almost all colleges (including all of the Ivy League, MIT, Stanford, Caltech etc.) as a substitute for the SAT reasoning test. In fact, some colleges even exempt you from the subject test requirement when you take the ACT instead of the SAT reasoning test.
