I can't see a course online that appears in the registration booklet.

1. Make sure that on the course search screen, you have the "course career" set to blank, rather than "graduate" or "undergraduate".

2. On the "Class Search Results" screen, make sure that you have clicked on "View All Sections" at the top of the list.

3. If this is a multi-section course, the department may have stopped enrollment on the particular section.  Please register for another section.
   

A course looks like it has open seats, but it doesn't appear on the registration screen.

1. DO NOT USE the courses search (http://chico.nss.udel.edu/CoursesSearch/) or quick course search (http://www.udel.edu/main/udsis-student/courses.html) pages; they do not display course information correctly.
   

2. Instead, use the class search/browse catalog page, which looks like this:
   

   
   

3. On the "Class Search Results" screen, make sure that you have clicked on "View All Sections" at the top of the list.

4. If this is a multi-section course, the department may have stopped enrollment on the particular section.  Please register for another section.

The section I want is full.

1. Because of the nature of the priority system, upperclassmen will be able to register for the most popular sections. However, the math department offers lecture-section combinations at a wide variety of times. If you find yourself shut out of your first choice, see if you can change other classes in your schedule and register for a different time.  In particular, our evening sections (-050 and -051) have many seats available, and fit in with most students' schedules.
   

2. Students shift in and out of courses all the time; check the system regularly to see if seats have become available.

3. Use the standard drop-add procedure during the first two weeks of the semester.  This involves bringing a pink slip to your instructor requesting that the section be overenrolled.  No exceptions to enrollment limits will be made before that time.
   

A course looks open, but it doesn't let me in.  ("reserved seats" error)

1. Certain courses, sections, or seats within sections are reserved for certain populations (often majors, but sometimes freshmen).  Some of these notations are made in the registration booklet; others in the catalog.  (These notations may also be seen from UDSIS by clicking on the course number when it's in your shopping cart.)  Others don't appear anywhere. 

   In many cases, these restrictions will be lifted after all registration appointments have been completed, or after Delaworld in July.  Check back after that time to see if you can register.
   

   However, it is quite possible that these courses will fill quickly.  So if you find yourself shut out of your first choice, see if you can change other classes in your schedule and register for a different time.

2. Verify that your major is listed properly in UDSIS.
   

3. In special circumstances (you are applying to a new major, you are the correct major but the system is locking you out, etc.), complete our Web form.

I can't register for a course: prerequisite error.

1. Carefully check the prerequisites, either by looking up the course online or checking the catalog.

2. Carefully check your transcript under UDSIS to see if it shows that you have the necessary coursework.  If you took the course at another institution, verify that the transfer-of-credit worked properly.  If you need coursework from an institution evaluated, see our Transfer of Credit page.

3. If you think that everything is in the system correctly but you still can't get in, complete our Web form.

4. If you are trying to substitute a prerequisite (MATH 221 for MATH 241, etc.), you will need to sign a waiver (available in 301 Ewing) before using our Web form to complete the actual registration.

Do I need to register for a lecture as well as a discussion and/or lab?  Which goes with which?

1. In classes with a lab, you register for the lab and it will automatically register you in the corresponding lecture and/or discussion.  In classes with discussion only, you register for the discussion and it will automatically register you for the lecture.  (All classes have a lecture component.)

2. The easiest way to see what lab sections go with what lecture is to look at the registration booklet.  Other places (like Courses Search) are much less clear.
   

3. The coupling between components is mandatory for math courses. That is, you cannot "cherry-pick" the lecture and lab---you must pick the ones that go together in the registration booklet.

I don't see all the class meeting times in my schedule.

1. In list view, click on the section number.  That will bring up a separate screen with all the meetings listed.

2. Switch to schedule view.
