Nothing is impossible. In fact, the content of senior one is irrelevant. As long as you pay serious attention to the third grade, you will certainly be able to bring mathematics together. When I was in junior high school, I always played in Grade One and Grade Two. Finally, in the third grade, I studied hard, consulted more teachers, understood what I had been obsessed with before, consolidated it by asking questions, did more questions and paid attention to finding ideas. In the senior high school entrance examination, I got the fifth place in the whole school, so the key lies in the third grade. Of course, it would be better if I studied hard in my sophomore year. Here's what I'm telling you: To put it bluntly, it's a process from known to unknown. You can prove the answer by giving you the known conditions, so you should pay attention to each condition and what are the known conditions to find the solution. For example, if I see a midpoint in the question, I will "double the length of the structure" or the midline, and so on. As for the summary of these methods, it is your reflection and accumulation in doing the problem. Think about it. Why use that equation instead of the equation method? Ask the teacher more, and you will gradually find that mathematics mainly pays attention to one method, and one method can help you 100 or even more. Actually, you don't have to be afraid of math. It's not that hard. Remember what I said, you will be fine. Don't be afraid, study hard and pay more attention to rest every day, which can improve efficiency. Don't be afraid, the next day is not that important. Take your time. You can make it up.
