First of all, unlike middle schools and primary schools, universities have teachers who urge you to finish your homework every day. University depends on your self-discipline and prudence. If you don't go to class every day and just ask your friends to help you sign in, your homework is written in a muddle and you don't finish it on time, then it will be difficult for you to pass the exam. University doesn't mean relaxation, it doesn't mean the end, it's the beginning of learning. On the contrary, if you listen carefully in class, do your homework well after class, don't be absent from work, don't be late for class, and don't play with your mobile phone, then it will be easy to pass the exam, because the purpose of university teachers is not to fail you (they are actually too lazy to make up the exam papers). Moreover, at the end of the semester, teachers usually give key points, and many questions are the original questions that teachers talk about in class.
Secondly, there will be no shortage of college courses. Unlike TV dramas, one or two classes a day are after school. Like me, there are only four days of public holidays, that is, one class is missing every day. There will also be elective courses on Saturday and Sunday, and there will be evening self-study for freshmen. Some schools have morning self-study in freshman year. Although classes begin at 8: 00 in the morning, each class is about 50 minutes, and all of them are large classes (all of which are aesthetic fatigue). High school thinks you can sleep in at eight o'clock, but college can't get up at eight o'clock every day.
Third, specialized courses in universities will be more difficult and deeper than those in high schools. At the beginning, you will often find that you can't understand and do the questions, and it seems that it has nothing to do with those in high school. Elective courses in universities are relatively easy to pass, but personally they are boring. The teacher said above, the students don't listen below, just to get enough credits.
Finally, if you just want to pass the exam and get the undergraduate diploma, you just need to work hard, but if you want to get a scholarship, take the postgraduate entrance examination and keep the postgraduate entrance examination, you must be particularly good, just like the third year of high school, even harder than the third year of high school. Our school has a small desk in the dormitory corridor in the middle of the night to study one or two points, and it is particularly obvious that there are two kinds of people in postgraduate entrance examination and postgraduate entrance examination. It depends on your pursuit.
