Yi Si is a software, and now it is a branch company in 800 yuan. So it is mainly self-study. There are concepts and exercises in it, and there are videos in the software, all of which are explained by the teacher. There are also classes, but often only a few days or so, so they are basically self-taught.

In mathematics. Their propaganda is mainly "50 problem groups", that is, dividing a class of problems into several topics, and then sorting them out for you by HowNet. They promised to "recite 50 problem sets, and the math in the college entrance examination must be 140, otherwise the money will be refunded."

I think first of all, they can't believe this guarantee. The college entrance examination is so easy to take 140, so what else can they take? All famous schools must have exaggerated elements. "Refund of fees" and the like are common tricks and are not credible. Their "50 problem groups" are reasonable, but we can't be superstitious. Traditional classroom learning is definitely the most important.

I think in their data, those who mainly go to them have made obvious progress and their achievements are in the middle. 150, you can get a little more than 100. If this is your case, you can think about it. If you want to keep improving, I think it's best not to choose this one, but to find a teacher who can solve problems face to face.

This is what I felt when I was listening to the class. For your reference. In addition, I am also a high school student. I think there are shortcuts when studying, but shortcuts can't take you to the top. If you want to climb up again, you still have to work hard.
