1. First count how many mistakes you made, then use the total score, that is, the total number of questions-(multiply the number of questions you made wrong by a quarter), and then there will be a reference table after the general questions. By comparing the numbers obtained from that formula, you can know the approximate number of points. Mathematics is a problem that requires all parts of mathematics to be wrong, so is reading and writing.

2. No, no, this is totally random. Only SEC 1 is always an essay. Everything else is different, and everyone in the examination room will not get exactly the same.

3. The missing SEC is an additional test. Additional tests are not fixed. It may be reading math or writing. It can be in any section and there is no fixed position, so I don't know what an extra test is when I take the exam. Do it carefully every second.

4. Eat, go to the toilet, sit in the seat or go out with the teacher watching. I can't read the information, but I can eat it.

About 40 yuan, I can't remember clearly. It's almost the same anyway. There is no extra registration fee. To register an account on COLLEGEBOARD, you can use credit card, visa card or MasterCard.

I hope I can help you! Good luck in the exam!
