When class numbers (call numbers) and section numbers precede the
hours and days listed, you may choose the section in which you wish
to register (see the first example below). Many courses have a choice
of laboratory or discussion sections, but only a single lecture section,
in which all students taking the course are automatically registered
(Example 2). This lecture section will have no class number (call
number) before it, signifying an automatic registration (see example
2, below), then your choice of laboratory or discussion hours determines
in which lecture you are automatically registered.
