If you study well and have enough time, the problem is not particularly serious. You can follow these two courses, but the speed will definitely be slower, so you have to take time out to study by yourself. If it is too difficult, you can find a math student to help explain it, and then sign up for a remedial class when the knowledge points are almost sorted out, so that the thinking will be relatively clear, and it will be better to grasp the key points and review. But don't start thinking about enrolling in remedial classes. It won't make any difference. On the contrary, it will make you feel very upset and lose information about yourself, because without foundation, you won't understand what the tutor said at all. Finally, give you some advice. Those who enroll in remedial classes can enroll in institutions of higher learning. The math tutor of the university is Mr. Huang Qinghuai, who used to be a graduate student marking group and has very rich experience. Universities also have online videos, which you can ponder and deepen your impression. Good luck!
