If you just accumulate the wrong questions in one book, it will be useless.

To accumulate, you can write down your own fault reasons and positive solutions below, and you should read them often (it is best to read them for a long time after accumulation), but when you read them, you'd better block out the answers and do them again. If you can do it right, you can put a tick next to this question and stop reading it in the future.

Moreover, the accumulated wrong questions are all due to insufficient analysis and other reasons. If a single number is miscalculated, there is no need to add it up.

Of course, the most important thing is persistence.
