Rice University in Houston, USA has classes five days a week, starting at 8: 30 in the morning and ending at 4: 00 in the afternoon. Three semesters, from September to 65438+February, from 65438+ 10 to April, from May to August, are all about 15 days' holidays. May-August is the legendary semester when you can skip classes (as long as you don't choose courses this semester), so people who study abroad usually return to China this semester.
