SAT

The SAT is a standardized test widely used for college admissions in the United States. Since its debut in 1926, its name and scoring have changed several times. Test of English as a Foreign Language is a standardized test to measure the English language ability of non-native speakers wishing to enroll in English-speaking universities. In comparison to the TOEFL the SAT focuses more on thinking for yourself and not understanding, which is why most colleges require both tests for the admission. While the TOEFL shows your English level as a non-native speaker. There are no specific eligibility criteria for the TOEFL exam prescribed by the ETS, the body that conducts the TOEFL test. Majorly, it is given by students who wish to get admission to universities, colleges, or educational institutions in English-speaking countries.

Your GPA is just one factor among a dozen or so colleges use to evaluate applicants. In many ways, I view test scores and course rigor as important, if not more important, than having an incredibly high GPA (3.75+) to be honest. For the school I read applications for, I would say a lower GPA is really anything under a 3.4 (though the avg for incoming is closer to 3.75). So if you had, say a 3.1, I would want to see a pretty good SAT score (1400+) and high course rigor (Andhra Pradesh, IB, Honors, dual credit classes) for me to dismiss the lower GPA. So, with high-test scores, your chances would improve of getting into more selective colleges (broad definition). .
