Class Numbers Explained

The following information explains the course and class identifiers in MyBU Student. Identifiers include course values, subject values, catalog numbers, section numbers, and class numbers.

This shows an example of a course as displayed in MyBU student highlighting the following identifiers that every BU course has: the subject and catalog number, which together make up the course, as well as the section number and the class number.

Courses are created with an identifier which includes the Subject and Catalog Number: ENGEK 103.
- ENGEK = Subject Area
- 103 = Catalog Number
Section Number: if a course has multiple sections offered, the Section Number will be listed in a ‘LetterNumber’ (A1) format. Note that there is flexibility for departments to include other identifiers after the ‘LetterNumber’ combination (as seen in this example): A1-LEC.
Class Number is a system generated identifier listed with the Section Number: 8688

Tip for Faculty: Faculty can find the identifiers for their classes in the Class Roster, Grade Roster, Teaching Schedule, or the University Class Search.
