Credits are the scores that this course can provide you, which are calculated into the graduation requirements. The credit system, which originated from Harvard University at the end of 19, is a comprehensive teaching management system with course selection as the core and teacher guidance as the auxiliary, and the quality and quantity of students' learning are measured by grade points and credits. Generally, American universities have four years and eight semesters, and the credits required for graduation are between 120~ 180 according to professional requirements. So you can take the 1~2 course, take the winter and summer courses and graduate early.

Class hours are units used to calculate students' learning weights. One credit is approximately equivalent to the amount of academic work 1 hour that a student does in a classroom or laboratory for one semester. It does not include extracurricular discussions, homework and exams between students and teachers or classmates. Under the two-semester system, 1 class hour is 1 credit.

In terms of semesters, most American universities adopt a semi-academic year and two semesters, namely autumn and spring. Full-time students need to complete more than 65,438+02 credits in one semester. International students with F 1 visa may be repatriated if they cannot guarantee 12 credits.

You can graduate early if you finish the credits ahead of time, but the tuition fee may not be saved, because another feature of the credit system is that you charge according to the credits.
