This proves that you have a good foundation, but you haven't figured out some problems to start the class yet.

In the next study, you should do some difficult questions to improve your level. Only in this way can your score be improved.

Or you are always careless about some details, which is the problem of the method of doing the problem. You should examine the questions before you answer them. Don't follow the previous process as soon as you see something familiar. You should read the questions before you answer them. After you finish, you should bring in the results and check them again, or push them from the conclusion to the conditions. The most important thing is not to lose information.

Hope to adopt, thank you.
