If you have completed the basic review before and have enough time and energy, you can start from the real question of 1997; If time and energy are limited, we can start from 2007, and the last five years are the most important.

1997 -2006 mathematics is still the content of advanced mathematics, so the mathematics part is of little reference value. Of course, there are some elementary math problems, which are relatively few, so you have to judge and screen them yourself.

The problem in 2007 -2009 is relatively simple.

The real questions about 10 since 20 10 are of great reference value. You can train your test-taking habits by doing the questions strictly according to the time of the test.
