Find a hidden study place. Many colleges have scores of buildings that are largely uninhabited after class hours. You’re paying for the ability to use the schools stuff.
Whether or not your friends or classmates choose to use the library, they are often filled with untapped resources. Need a book? Most libraries will order books or other materials for you free of charge. Most libraries also have a variety of journals, periodicals, and events that can be great ways to go beyond just school work.
Always go to class. Period.
