Personally, I think the red tick is more difficult than the college entrance examination, but the topic involves many new methods and is worth practicing. The teacher must have a purpose in asking you to do it. I think these topics are of great help to the students in the upper and middle reaches, so I need to do some. Don't lose heart when you encounter a difficult problem, try to solve it. Although it is very troublesome to do, it will have a great sense of accomplishment and will improve you subtly. As a science student who just came from senior three, I think what you need to learn is the method of solving problems, and you should try to sum up everything. I believe you will improve greatly, and I wish you all the best. Finally, I want to say that according to the practice of previous years, the single subject topic of last year is difficult, and the subject topic of next year is simple. I wonder what your college entrance examination is like? I hope you have enough confidence to meet the college entrance examination. Come on!
