I'm not from Guangdong, so I want to express my views on the inconvenience of the local college entrance examination, but as an experienced person, I want to express my views on your confusion.
I am a liberal arts student myself. I think if liberal arts want to widen the gap, mathematics must not be too bad. But in learning mathematics, girls have no advantage over boys. This is a reality that must be faced squarely. However, there is no need to repeat this truth, I believe you understand. Of course, you need to practice more and know how to learn math well. You mentioned the wrong problem set, which is really necessary. Sort out the wrong problem sets and look through them more often. In addition, if you can tell your classmate what you know, he will understand, and you will have a deeper understanding of this topic.
Speaking of politics, I don't think politics is very difficult, because there are rules to follow in answering political questions. For example, to test philosophical principles, you only need to understand the meaning of the question and know what to test. You just need to set the format, put the theory first, and then combine the material with the argument. Other topics should also sum up the rules.
Chinese poetry appreciation and reading questions are subjective and difficult to grasp, but teachers who also change papers will not give zero easily, because as long as you answer, it is impossible to be unreasonable, so the answering skills mean the golden mean, such as the artistic conception of poetry fully expressing the author's feelings, and the creation of artistic conception sublimates feelings. In addition, we should master some fixed statements, such as Li Shangyin saying that his poems are obscure and good at using allusions, and Du Fu's style should be recorded as cadence and so on. If you really don't know what to say in the reading questions, just sort out the relevant contents in the original text.
If you want to increase your fighting spirit now, I suggest you read some biographies of celebrities and some inspirational books. Of course, I think the most direct way is to listen to some related speeches or lectures. A passionate speech will definitely cheer you up, and maybe your mental outlook will be completely new.
Other problems, I think most girls exist. In view of the delicate and complicated psychology of girls, I won't say much and have no right to speak. But from your question, I can see that you are a confident person, and I believe you can handle the relationship between individuals and others as well as the collective. I wish you an ideal result in the college entrance examination ahead of time and a successful study!
