I highly recommend that you take either one one them within your junior year in high school.
You can take both if you choose to do so. In the end, you can report the best score out of the two tests.
Two tests are SAT and ACT.
Yes
Either the SAT or the ACT and most big, prestigious schools like Boston College require at least 2 SAT Subject Tests
The SAT's or the ACT's.
Both tests are college entrance tests, but it depends on the college. Some require only one, and some will take either.
take both bro
Sat, satII, and act
Hi, SAT and ACT are entrance tests, while board exam in India is similar to a high school graduation in US. SAT and ACT are entrance tests like AIIMS, JEE, CLAT etc.
If someone takes multiple ACT tests, then they Superscore them, meaning they take the best subsections on each of the tests and come up with a new composite. But keep in mind that MOST colleges and universities DO NOT superscore the ACT and only the SAT including all of the Ivy League and UC schools.
It is certainly possible, and actually quite common, to take both the SAT examination and SAT subject test(s) in the same sitting. If you choose to take that route when registering, after taking the standard SAT, you must touch base with a proctor, who will then take you to your subject test. Common subject tests include Chemistry, Math II, and various foreign languages. Subject tests are typically not required, or can be replaced by the ACT, for college admissions purposes. Their traditional value has come in determining placement into intro college courses.
