Most students should have their schedules finalized before the wait lists are erased. For the remainder of the drop/add period, adding any class requires a permission number.
Note that adding a class at this time is often difficult, as that class will have covered already a substantial amount of material, and written assignments will have been collected. If you are allowed to add that class, you will have to make up all of that missed work, probably on your own -- while also doing the continuing work for the course, and keeping up with all of your other classes. Students should consider carefully the question of whether accomplishing this is realistic, and be aware that being unsuccessful in such an attempt would probably result in a poor performance in that class.
Instructors are also keenly aware of this issue; accordingly, instructors are within their rights not to accept further students into their classes. The Mathematics Department might also conclude that adding a course at such a time would not be appropriate, and not allow a student into a course. Adding a lab calculus course after the wait lists are erased is particularly problematic in this way due to the lab schedule and class content.
Another difficulty is that, of course, the class you are interested in might be full. Be aware that the Mathematics Department usually does not allow students into sections that are full.
If you are interested in adding a class during the drop/add period after the wait lists have been erased:
- If you are already enrolled in a different section of that course, if you have been doing the work for the course, and if there are seats available in the section you want to switch to, contact the instructor of the desired section to request a permission number.
- If you have been attending a higher level course and want to "drop down" to a lower level course (for example, from Math 122L to Math 111L), and if there are seats available in the section you want to take, you should discuss your case with the Supervisor of First-Year Instruction. Be aware that, depending on details, it may be too late to add the course. (See discussion below on Changing Classes.)
- If you want to move up to a higher level course, you should discuss your case with the Supervisor of First-Year Instruction. You will need to establish that you are qualified for the higher level course; see the Placement Page for details. You will also need to establish that you will be able to catch up on missed material and work in a timely manner. Be aware that, depending on details, it may be too late to add the course. (See discussion below on Changing Classes.)
- If all open sections of the desired course conflict with required classes in your schedule, you should discuss your case with the Supervisor of First-Year Instruction.
When you contact either the instructor or the Supervisor of First-Year Instruction (as directed above), please be sure to include all of the information necessary to establish that you are qualified for the course, as described above. (See the Placement Page for discussion on placement qualifications.)
Recall that time is a very important factor in deciding if it is advisable for you to add a class, so you are urged to follow the instructions above as soon as you can. For example, a request to add a class late in the second week of classes is unlikely to be granted.
Once you have received a permission number, please add the course PROMPTLY. Be aware that until you actually enroll, there is the possibility that the section might fill up and you might be denied entrance into that new section. It is not appropriate to request a permission number that you do not intend to use promptly.
