Most prestigious universities require SAT II grades. Most students choose to take SAT II courses in two classes to suit their aptitude, but Harvard and other top universities are better off seeing at least three subjects in SAT II. In addition, other subjects except Math IIC and Math IC subjects are difficult subjects that can not easily be scored high, so it is a shortcut of high scoring to go through thorough basic course and preparatory learning from the beginning.
Most students tend to watch the AP test as they compete, so if all the other students do not pay for the AP exam, it can be disadvantageous. So if you study AP and SAT II at the same time, I can say that.
The SAT Subject Test is a test that requires the student’s knowledge and skills in special subjects. It also identifies how students use knowledge. Through SAT II, students can show how well they have mastered their elective courses at university. The exam is an independent exam from a special textbook or tutorial. The content of the exam reflects recent high school subjects, but the exam questions change annually. Many universities require SAT subject exams.
