In the college entrance examination, the total time for choosing math fill-in-the-blank questions must be completed within 45 minutes, and a certain accuracy should be guaranteed. Generally speaking, the last question is difficult to choose. If you try your best, you can't give up and do the big problem that is easier to get points later.
Only the last two big questions are very divided questions, and all other big questions are basic questions, so you must get full marks. Generally, the first question of the last two questions is relatively simple, and the next few questions will not be empty, leaving 10 to 15 minutes to check.
