Secondly, judging from your weakness, most common problems of mathematical series can be solved by everyone. If it is a clever method, I personally think it still needs some talent. If the landlord is not very good at this direction, he must determine the basic points and try to divide the process into criteria.
Third, most languages are accumulated for a long time, and the possibility of progress in the short term is limited. I have always felt that Chinese is an intuitive subject. I suggest reading several articles in recent days to find out my feelings, but I don't necessarily insist on prose. There is no need to constantly add psychological hints that I can't understand prose. I can read 1-2 all kinds of articles.
I feel that the landlord's grades are not bad, except for math. Don't be too anxious. To say the least, there is actually limited room for improvement in the short term.
Finally, you didn't make any mistakes on any topic you know, which is a great achievement.
