2. Understanding of money. There is no doubt that it costs a lot of money to sign up for classes. For example, I have a classmate whose family situation is not bad enough to afford, but she thinks that the tuition fee is too expensive and not worth it. However, I think the postgraduate entrance examination is related to the future and the future life. For some people (such as me) who are not very good at undergraduate courses and want to change their destiny, it is as important as the college entrance examination, and its difficulty is far above the college entrance examination. So I think the money that should be spent still needs to be spent. Now that you have made up your mind, it's better to treat it as a venture capital, with your efforts as a bargaining chip. Perhaps the investment at this time will get a hundredfold return in the future (no exaggeration).
3. Your undergraduate course. If your undergraduate course is in 2 1 1 and 985 universities with strong learning atmosphere and first-class resources, it means that you have the following advantages: (1) good foundation (2) strong learning ability (3) excellent teachers (4) strong learning atmosphere. In this case, it doesn't matter whether you report to class or not, it depends on your own wishes. But if you are in a general university (such as myself) other than 2 1 1 and 985, especially in a science and engineering school (the learning atmosphere is weaker than that of a normal university), I deeply understand that it is better to enroll in classes.
The above views come from individuals, hoping to give some help to every student who feels confused and at a loss on the road to postgraduate entrance examination. Finally, I wish you and yourself all the best. Fight for your dreams!
