Every exam should sum up your mistakes, not superficial, but fundamental.

I'm going to write the wrong set of questions again I always thought it was useless to write this when I was in primary school, but I found it very useful when I got to middle school!

You should write carefully and write down the wrong questions, positive solutions and the truth of each question. Then you'd better find some similar questions to do and do them again every few days to see if you can practice again!

That's what I did. I got more than 70 points in the primary school math test. In junior high school, you will find that the six-year primary school has been completed in half a month! It is really simple. In addition, don't care too much about your grades, pay attention to your attitude and be good at digging up the reasons from behind.

Finally, I wish you good grades and improve your math scores as soon as possible!
