The Time Schedule is the listing of course offerings each quarter. UW's Time Schedule is available only online; there is no printed version.
The Time Schedule for a particular quarter is available about a month before Registration Period 1 (current student registration) begins.
Reading the Time Schedule
Courses in the Time Schedule are listed alphabetically by college (Arts and Sciences, Business, etc.) and then alphabetically within each college by department. If a course isn't listed, it isn't being offered this quarter. Check the Course Descriptions for listings of all classes offered regardless of quarter.
The colored title bar lists the abbreviation for the department (e.g., in the below sample, PHIL = Philosophy); the course number (e.g., 120); the title (e.g., INTRO TO LOGIC), which is linked to the course description, including prerequisites; requirements this course fulfills (e.g., PHIL 120 counts for Quantitative and Symbolic Reasoning and either Individuals and Societies or Natural World; and whether the course has a prerequisite and/or has cancellation in effect (not seen in this sample).
Some UW courses are offered as combinations of lectures and quiz sections, which are small discussion groups, usually led by a TA (Teaching Assistant). In the sample below, PHIL 120 is a lecture class meeting MWF 10:30-11:20, with quiz section meetings at various times and locations on TTh. You choose only one of the quiz sections. To register for PHIL 120, you'd need the SLN for the lecture (e.g., 16698), and an SLN for one of the associated quiz sections (e.g., 16699, 16700, or 16701)
Some courses have more than one lecture offered. Lectures are always indicated by a single letter (e.g., in the sample above, "A"). Further lectures would proceed with B, C, etc.
Each lecture has its own quiz sections. Just as the quiz sections that go with lecture A are called AA, AB, AC, etc., the quiz sections that go with lecture B are called BA, BB, BC, etc. In choosing a lecture/quiz combination, you must choose a quiz section that begins with the same letter as the lecture. That is, you cannot have lecture A and quiz section BC.
Open/Closed Courses
The sections of each course that are closed (full) are shaded out. This shading is updated only once each day, at midnight, so it might not be correct at the moment you are reading the Time Schedule. But it does give you an overall idea of how things are going. In the sample above, sections AA and AC of are shaded out as closed.
For the Current Section Status of a course, click on the schedule line number. This takes you to more detailed information about the course and the "real-time" enrollment status. PHIL 120 AA was closed when the Time Schedule was updated at midnight, but it may be that when you click on the SLN you will see that the course is now open. Similarly, a course that looks open may in fact now be closed, and you will see that if you click on the SLN.
Another way to check for open and closed classes is the Enrollment Summary. To get to the Enrollment Summary, click on the Enrollment Summary link in the top right corner of each department's Time Schedule listing. The Enrollment Summary is a list of the courses offered by the department with the current (real-time) enrollment status of each section of each course.
Registration Restrictions
UW courses often have restrictions on who can register for the course, and when. The restrictions are all listed in the Time Schedule. Some are visible in the regular listings, and some are visible only if you click on the SLN and look at the detailed information. If there are any restrictions, there will be a "Restr" note in the first column, to the left of the SLN. For explanations, see Registration Restrictions.
Courses that require an entry code (add code) have a ">" just to the left of the SLN.
Additional Information
There are built-in links to additional information about courses in the Time Schedule. Each course title is linked to the Course Description of the course, where you will find any prerequisites listed. The building abbreviations link to campus maps. If the instructor has prepared an Instructor Class Description, with more detailed information about the course, there will be a link from the instructor's name.
If you click on the SLN, in the Current Section Status there is a link to the textbooks required for the course.
