Finish all the questions as soon as possible!

I won't do it. Keep it for the first time!

I won't do the second cleaning, and I will consider each question for 2-3 minutes. I won't just write a few possible formulas on it and then pass them decisively, such as the finale.

There should be plenty of time for the third time. Do the basic questions again to avoid looking at the previous answers. Compare it twice and pass the same test. If not, check it carefully.

The fourth time, check the test paper to see if there is any blank space, title, name and test number on the back.

The fifth time, continue to do the basic questions again. Answering questions requires a writing process, but the error rate is low. )

When you get the test paper, please be as decisive as adopting this suggestion, asking for nothing but nothing!
