After the math exam, the estimated score was similar to that of my deskmate, but in the end, her score was higher than mine?
Listening to others say that doing wrong questions is the way to use them, I started to buy a book and copied the questions on the wrong book;
The wrong book seems to have written a lot, but it doesn't seem to have much impact on your math scores;
This kind of scene, whether on yourself or others, should be common.
In fact, the most fundamental reason is that you don't understand the purpose of making the wrong question book. If you can't get the essence of it, you will naturally fall into a cycle. Copying the questions in the wrong book → Mathematics has not improved → (It should be said that you haven't persisted in copying the questions) → It's still useless → Giving up the wrong book, which is a serious blow to your self-confidence, and you may feel that you can't learn mathematics well all your life.
In fact, it is very desirable to learn from other people's good learning methods, but how to adapt it to our own learning rhythm is what we really should do.
Since the wrong question is a good way, let it really be used for yourself.
