I t is easier. There are less students around campus and in class. You get to know the professor better. Summer Session provides the opportunity to get ahead and actually make decisions like double majoring, or retaking a class to get a better grade.
Classes are smaller, more personal.
There is less stress due to less class load. You can get a course requirement fulfilled in a just a few short weeks. It is possible to take only one class during a session so that you can better focus on that class and do well. It is also nice to be given the opportunity to take something in order to catch up on classes that you are behind on or did not do well in. Getting into classes that are hard to get into during the school year, getting ahead or catching up in my major classes.
