Getting it right is not the goal, but the key is to study his thinking of writing questions. He decided not to force you to do it. There are rules to follow.
After five years of real questions, you can do the simulation questions before the middle school entrance examination. You must have them. At this time, you almost have your own ideas, and you won't be fooled at first sight. However, those simulation questions are crooked, and only the mid-term exam questions are passable. Don't deliberately study the routines of simulation questions. They drink different exam questions. That's all. The key is to practice by yourself.
Also, you can't keep doing it just because the foundation is not good. If the foundation passes, the paper can be close to full marks.
Because you can't switch between knowledge points instantly. For example, the problem of geometric figures should be related to trigonometric functions, isosceles angles and so on, and then to modeling. There are too many things to do.
So summary and reflection are the key. One question every day, review every other week, and then do new questions.
