I think everything should have a reason.
Now that you have chosen to repeat, you must decide. Senior three has had one year's experience, so it's useless to be impetuous.
It is good to know your own shortcomings.
Don't worry too much. Use the time you are worried to do something useful.
Since primary school, mathematics has always been my favorite. I can't tell why I have such a soft spot for mathematics, perhaps because I like to challenge difficult problems, or perhaps because I am happy after solving them.
But the only change is that math used to be my strong point, and I can get a lot of points in a math exam. But not now. Maybe the more knowledge you learn, the harder it is, or maybe the people around you are getting better and better.

No matter what I study, I think interest is the best teacher, and mathematics is no exception. When you like math very much, it is like a big sweet cake in front of you. What you have to do is not to swallow it at the fastest speed, but to taste and understand every little knowledge point slowly and thoroughly. Don't worry, take it little by little. Practice hard, ask questions that others can't, and read books repeatedly. ...
In fact, there are many ways to learn, and the one that suits you is the best.
Hehe, I am a senior three this year. It is very important for all the children who take the college entrance examination next year to strive for every minute before the college entrance examination. Come on, I hope I can live up to my senior year.
