There are thousands of universities and colleges in the world offering education. These colleges and universities offer many courses in many fields. Once when a person is enrolled in a course, there are various things one should know and understand before taking up a course or choosing a university, school, or college to study. Various systems are used to split up the academic year of any educational institution.

Every academic year is split into three semesters, the fall semester, the spring semester, and the summer semester. The fall semester and spring semester are 15 years, but the summer semester lasts for only 12 weeks. The summer semester lasts for 12 weeks because it is optional. While colleges and universities split their academic years into 3 semesters, schools normally split their year into four quarters.

The quarters are split into fall quarter, winter quarter, spring quarter, and finally, summer quarter. Every quarter corresponds to the four seasons and every quarter lasts for 10 weeks. Trimesters are not as common as the other two, but there are some schools, that offer trimesters. Trimesters last for 12 weeks and they are split up into fall, winter, and spring trimesters.

Why Is Semester Long That?

Some schools offer another quarter, so they are slightly similar to quarters. Most of the colleges all around the world follow either the semester or quarter system, yet the semester system is the most commonly followed one. There are various reasons why students choose educational institutions with semester systems. The semester system gives the students more space and time to learn.

It also helps the students to build a good relationship with their teachers. Quarter systems, on the other hand, offer more flexibility for the students to pursue any other course other than their main career choice. Clearing semesters with good credibility can really help people advance in their careers. According to facts, about 95% of the U.S educational institutions follow semester systems.

An average student takes about 4 to 5 courses every term, which will earn them around 15 credits totally. Normally, the first semester begins every year in the fall semester. It begins in late August and the final semester ends in May, which is the spring semester. Summer semesters take place afterward.

There are many pros to choosing the semester system to study. Students have more time to learn and study, complete assignments. The extra time provided can be really helpful for graduate students since they have long assignments. The transition is very much easy with semester systems because the timings align very much well with the end of school and community colleges. It helps the students to cope up well with the university.


The class periods are very much shorter than trimester and quarter system classes, and normally each class lasts for around an hour to an hour and fifteen minutes. The connections formed with the faculty and professors are very much stronger than the ones in the other systems. It helps the students with their recommendations and advice about jobs and careers.

There are multiple drawbacks to the system too. Sometimes, when one wants to switch courses during a semester or after, it can be really costly. One will have to pay for the courses they didn’t even graduate from. It is also very hard to increase the CGPA, as the credits can decrease and increase easily.
