Unit Weights and Degree Requirements
Courses are assigned unit weights, which vary from 0.25 to 1.0 credit or more. Most one-term courses have a 0.5 unit weight except for lab courses, which are generally 0.25 unit each.
Course unit weights are used to calculate weighted averages as well as the tuition fees payable for the term. Part-time students especially should be aware of this fact when choosing courses.
Students should read individual Faculty regulations carefully to be sure that degree requirements are understood and met in the manner required.
