A large university is not necessarily better than a small college. Though large institutions may have more facilities, they are likely to seem impersonal compared to a small college. Also, not all of the programs offered by a famous university are of the same quality. When you choose a school, you should find out something about the reputation of the program you have in mind. As a rule, one credit represents one hour of class time a week for one term, except in the cases of language or laboratory courses, which require up to two hours per week per credit.
Most courses are worth two, three, or four credits.
Full-time undergraduate students usually take 15 credits per term. These degrees are divided into two categories, arts and science. The former is mainly for humanities and social science and the latter, for natural science. Generally, a bachelor of science degree, for example, requires more credits in the are of the student's major than a bachelor of arts degree does. It is not unusual for students to change majors.
