Math level 2 ***50 questions, the fault tolerance rate is about 5 (SAT2 Math includes 1 level and level 2, so I suggest you choose SAT2 Math level 2 exam);
Physics ***75 questions, the fault tolerance rate is about10-15;
Chemistry ***85 questions, the fault tolerance rate is about 4;
There are 90 multiple-choice questions in American history, and the fault tolerance rate is about10;
Biology ***80 questions; There are 60 questions in the public part, and students choose 20 questions (M in molecular biology direction and E in ecological direction). The fault tolerance rate is about 3~4.
Calculators can only be used in math exams, but not in other subjects. We recommend two calculators (scientific calculator: Casio fx-99 1 CN) or (graphic calculation: Texas Instruments TI-Nspire), which are the most powerful and convenient to use.
All the subject questions are on a test paper, and the cover will have the page number of each subject question. If you take multiple exams and complete one subject every hour (not across districts), the order can be arranged by yourself. Take a break of 5- 10 minutes between exams. You can leave after you finish the exam yourself.
For Asian students, a score of 780 or above in mathematics and 750 or above in physics and chemistry at the time of application is more competitive, and the requirements for China students are higher. Students who apply for prestigious schools suggest 2400 marks (800+800+800) in the three subjects of Mathematics, Physical Chemistry. American history, English literature and biology are difficult to test, even if the score is slightly lower, they will be very competitive.
