SAT 1 is a traditional sat, which is a required test for applying to American universities. SAT 1 cannot select subjects. One exam includes math, reading and writing, with a total score of 2400. Writing is divided into grammar and articles; Reading is divided into vocabulary and reading articles. An exam takes about 5 hours.

SAT2 is a single SAT test, including mathematics, physics, American history, literature, and various foreign languages. You can choose at most three doors at a time, each door 1 hour, with a full score of 800. Testing generally adopts the strategy of 2 out of 3.

In addition, SAT 1 and SAT2 cannot be tested in the same exam. For example, take the SAT 10 in June, and only take the SAT2 in June 1 1. SAT 1 is obviously more important than SAT2, because not many American universities need SAT2 scores.
