Generally speaking, according to the situation of specific schools, you must take enough credits when you graduate. If the school doesn't limit the credits you can take each semester, you will spend all your spare time taking elective courses and taking credits except the courses arranged by the school. But I'm really tired, and there's not much difference between senior and senior. For example, our school has regulations on elective courses, except for the courses arranged by the school, you can't take them yourself. I must obey the arrangement of the school every semester until the third year of high school.

If you want to take the postgraduate entrance examination, you don't have to finish all the credits in advance. It's easier for me to follow the requirements of the school. In addition, it is good for you to review alternately in junior and senior years. Otherwise, it will be difficult to keep reviewing. If you take this major, some courses are already very important for the postgraduate entrance examination. Wouldn't it be better if you went later?

It is necessary to be too nervous. Step by step.
