The time of college classes is very irregular. As far as my situation is concerned, I still have early self-study in my freshman year. Every morning, self-study begins at 7: 00 and ends at 7: 30, and it has been gone since sophomore year. Universities usually arrange up to four classes a day, sometimes five to six. If there are classes in the first class, the first class will start at 8: 30 and the second class will start at 10: 30 in the afternoon. The first class starts at 1: 30 pm and the second class starts at 3: 30 pm. There are also some special circumstances, such as the school requiring you to have elective courses or your instructor to add classes, so there will be classes in the fifth and sixth classes.
