First of all, math 1 is indeed more difficult than math 2 and covers more content. If you have already prepared for Math II and mastered it well, it may be a challenge to switch to Math I. However, if you already know something about Math and feel that you can meet the challenge, then this decision may be feasible.
However, you need to make full use of the remaining time to study and prepare for Math One in an all-round way. This may include mastering new knowledge points, doing more exercises and simulations, and studying and discussing the relevant materials of mathematics 1 in depth.
In addition, apart from the differences in difficulty and content between Math 1 and Math 2, it is also necessary to consider whether the study time of other subjects is enough. Because it may take more time and energy to switch to Math I, it may have a certain impact on the study of other subjects.
In a word, if you have decided to try to switch from Math II to Math I, you should act immediately and make full use of the remaining time to make full preparations. At the same time, we should also pay attention to the reasonable arrangement of time to ensure that the study of other subjects is not affected.
