There are so many questions in the college entrance examination every year, which are almost the same. I suggest you find a professional counseling institution to study. Offline is a waste of time and energy, mainly because you don't have time, the cost is high, and you can only listen once. Personally, I don't feel very good and I'm under too much pressure. I spent a lot of money to sign up for work, but it didn't work. The main reason is that the pressure from the school is enough. I'm a senior three now. Every simulation is basically above 130, because I introduced the online course last year, and now it is convenient and low cost. Moreover, I can't listen to it once, or I don't have time to listen to it on the spot. I can listen and listen repeatedly, and the teacher has a good attitude. I signed up for wavelet mathematics and found it online, which is very helpful to me. They said I would take the college entrance examination next year.
