It's just that I'm not good enough, but this score comes from my carelessness and attitude at that time. For example, the problem * * is a calculation problem. If I had looked up more myself, I wouldn't have asked this question. Even if you don't have time to look it up, it won't be like this if your basic skills are better. But after all, the exam depends on your own efforts and intentions, and you can only blame yourself for getting this result.
But I won't give up on myself, and introspection will only be like boasting. I will definitely prove my reflection with practical actions. From now on, I will study harder and try to get rid of my carelessness. Live up to the expectations of classmates, teachers and parents.
