That's all bullshit. Look at the amount of questions they do, you must collapse immediately. That sounds horrific.

Therefore, the most important thing for people who are not good at math is to ask questions, and it is a huge sea of questions. The more, the better.

I have summarized the following experience for your reference.

Learning (for any subject) can be divided into four stages.

Accumulation period, rapid growth period, bottleneck period and invincible period.

The most painful thing is the first stage: the accumulation period. During this period, you will find that your efforts and gains are completely out of proportion and your grades are extremely poor. At this time, you need your amazing perseverance and great fighting spirit. Never give up. The period depends on the situation. For mathematics, it is violence to do problems, not just to do problems, but to do problems.

In the second stage, you are often very excited. At this time, you will fall in love with math, because you will go crazy if you do a little casually, so don't worry.

The third is the bottleneck period, you will find that no matter how hard you try, you can't get on, so don't do it again, because it's useless to do more.

At this time, you have to do something much more difficult than yourself, such as studying English in the college entrance examination, then you can do Band 4, and math is a competition. Once you get back to the original level, you will find that everything you do is so simple. Actually, this is very simple. Now look at your elementary school math paper and you will know what it feels like.

In a word, asking questions is a good way to solve the exam. Wish you success!
