The wrong title is also necessary, after all, it is a summary of past experience. But the function of the wrong question book is not to record the wrong questions, but to remind yourself not to make the same mistakes twice or more.

It is recommended not to spend time preparing the wrong book repeatedly, because there are bound to be many repeated mistakes. It would be great to thoroughly understand all the previous wrong books, remember the wrong places one by one, remember the routines and eliminate them one by one. If you think it's probably wrong again, just copy it (well, it's a new book, but it's already the essence).

For example, to explain the degree of "thorough understanding" is to see which question in the wrong book is the same or similar to the wrong type and the correct way to do it. Yes, I mean basically knowing what every question in my wrong book is saying, what is the routine of each question, and knowing everything. . .

Yes, I won't make the same mistake again in the future. When I see the question, I will know how I missed it before. At this point, the wrong question is completely in my mind.

I used to do the same in biology class. In the end, everything is routine. . Well, unless there is a new reminder, variants are all small case.
