Mathematical errors may be classified by units, such as sets, functions, sequences ... and then a synthesis is established for those that are not well classified, so that it is convenient to check, or targeted training can be carried out in the future.

I haven't found a good classification method for English wrong questions. English is too fragmented. It is best to mark those that are considered to have special value according to the records and read them completely before the exam. As for the correction of cloze reading, we should also write down the most classic ones. But it is best to have a recent college entrance examination paper, which is the best information.

The significance of political misreading is not particularly great. One trick our teacher teaches is that there are always some typical mistakes in political objective questions, such as "consciousness plays a driving role in the development of things".

But I think it's enough to understand the geography topic. If you have any important points, you can write them down in your notebook.

There is no need to make a mistake about Chinese. Sort out the pinyin Chinese characters, and then make up the mistakes.
