There is no fixed number of doors, you can choose, you can repair more or less. The policy of each hospital may be a little different. We graduated with 17 1 credit (including graduation thesis and social practice) and completed the course in four years. General courses have 1-4 points. You can do your own calculations and arrange your own time. Many people graduated with more than 200 points, and many took double degrees. Generally speaking, if there are few courses, there are 6-8 courses a semester, and if there are many courses, 15+. If you finish ahead of time, of course, you can do less in senior three.
