Lehigh classes have two rounds of exams, and each are called 4 o'clocks, named for the time they are administered to students. Giving exams at this time allows all sections of the larger classes, such as Economics 001 or Calculus 21, to take the exam at the same time.  Also, to students chagrin, it allows professors to continue to use class time to continue teaching new material in class.

In recent years, a number of stress-reduction activities have been added to help students cope with the extra academic pressure.
