Enrollment FAQ

Notes:

  1. Prerequisites are not enforced at enrollment in all courses. In some, students are de-enrolled instead. In others, enrollment is unrestricted and the prerequisite background is assumed.
  2. Not all Course Directors are willing to consider issuing permissions to enroll.
  3. Not all courses maintain enrollment waiting lists.
Students on a Letter of Permission, exchange students, students with transfer credits: Why can I not enroll?
Unfortunately, the enrollment system does not know about transfer credits or background preparation at a different university. To get around this, please use the appropriate form. Your status will be checked and if the background preparation is verified, you will be given permission automatically. Otherwise, the course director will be asked to approve your request to enroll.
Students missing prerequisite courses: What can I do to enroll (or not be de-enrolled)?
In some courses, prerequisites are enforced. They can be enforced at enrollment or (if that is impractical) afterward by de-enrollment.
If you are prevented from enrolling because of missing prerequisites or if you are enrolled already and do not want to be de-enrolled later, you will need permission to be (or to stay) in the course. To get permission, please use the appropriate permission form. If you are not enrolled and space is limited, permission to enroll may be delayed until all students who have the prerequisites have had a chance to enroll.
What does it mean when seats are reserved?
  • This can occur if your degree program does not require this course and priority is given to students needing the course when space is limited. If that is your situation, you will probably be able to enroll later, once all priority students have had a chance to enroll. Near the start of the course, any remaining spaces are freed to open enrollment.
    Since enrollment times and dates are different for each student depending on their major and year level, you need to keep trying each available lab and section as students are constantly changing their timetables, even well after the course has started. As well, the department is constantly monitoring for students who are not entitled to enroll and for students who are entitled to a lab exemption, while liberates seats all the time. You will have a better chance of enrolling into a class during the first week of classes, when the reserved seats are released and you may be able to trade lab sections once you are enrolled. Students with the needed prerequisites are almost never denied enrollment, though it may only occur late.
    Enrollment for 2020-2021
    Please note that the wait lists for CHEM 2020 and 2021 for Winter 2021 will re-open in December. Most enrollment restrictions for CHEM 2020M (W 2021) will be lifted in December (no precise date has been chosen yet) and the remaining reserved spots will be released at the start of term. New spaces will also be added as demand warrants.

    Note that the Chemistry Department does not manually grant permission.
  • Otherwise, it may be that the priority spaces apportioned for students in your major have all been taken. The numbers used are based on previous years' distribution of majors needing the course. In that case, it may be that the distribution of priority seats needs to be adjusted, and those adjustments are made on-goingly. If you have the prerequisites and are unable to enroll, you should contact chemasst@yorku.ca with details.
Do I need to repeat the labs if I'm repeating a lab course? Can I enroll into lab 99?
If the course is being repeated, it is possible to be exempted from lab work in most lab courses if the labs were performed and passed. The grades earned for earlier lab work will then be carried forward even if the grading of the exempted lab sessions has changed.
Lab section 99 is reserved for York University students repeating the class and students cannot directly enroll in that lab section. To request enrollment in lab 99, please use the appropriate form.
Please note the following:

  • CHEM 1000/1001: Lab exemptions are granted only if all labs were performed and passed within the previous 2 years.
  • CHEM 2020/2021: Full lab exemptions are granted if all labs were performed and passed. Partial exemptions may be granted if a few labs need to be done.
Why have I been de-enrolled?
There are a few reasons why this can happen:

  • You don't have the prerequisites. Some courses enforce prerequisites at enrollment. Others do not but enforce prerequisites after enrollment by de-enrollment. This can happen for instance when students should be able to enroll into a course while still completing a prerequisite course but do not succeed in that prerequisite. The only way to enroll in this course is with permission. To obtain permission, please use the appropriate form.
  • Your prerequisites are transfer credits or you are an exchange student or on a Letter of Permission from another university. Unfortunately, the enrollment system does not know about such situations. If you have not done so already, get permission to be (or stay) enrolled using the appropriate permission form.
  • You have attempted the course at least twice before and now need permission to make another attempt. This is pretty much guaranteed but you need to convince the Undergraduate Program Director that you are serious about succeeding. You can initiate that process with the appropriate permission form.
I'm a visiting student who was accepted on my Letter of Permission. Why can I not enroll?
If you have the prerequisite background from your home university, contact the Undergraduate Program Director at chemupd@yorku.ca about the issue. If you need no prerequisites, then it may be simply that enrollments are apportioned according to priority. No one who needs and deserves to be enrolled is denied. Since enrollment times and dates are different for each student type, depending on their major, you need to keep trying each available (lab and) lecture section as students are constantly changing their timetables. You will have a better chance of enrolling into a class during the first week of classes, when the reserved seats open up.
The system says that I don't have the prerequisites, even though I have transfer credits.
The online enrollment system unfortunately does not recognize transfer credits. Please contact the department at chemasst@yorku.ca or 416-726-2100 ext. 5246 or directly at 416-736-5246 so that an over-riding permission can be issued.
I'm an exchange student. Why can I not enroll?
The enrollment system has no prior record of background, so prerequisites are not known. Simply contact the Undergraduate Program Director at chemupd@yorku.ca to get around this issue.
What does it mean when seats are reserved in CHEM 1000 or 1001?
  • This will usually occur because your degree program does not require this course and enrollments are set to accord priority to students needing the course. If that is your situation, you will probably be able to enroll later, once all priority students have had a chance to enroll and near the course start, as any remaining spaces are then freed to open enrollment. Please note that, since enrollment times and dates are different for each student depending on their major and year level, you need to keep trying each available lab and section as students are constantly changing their timetables, even well after the course has started. You will have a better chance of enrolling into a class during the first week of classes, when the reserved seats open up. Students with the needed prerequisites are almost never denied enrollment, though it may only occur late. For further details, please visit the first-year chemistry office in 102 LSB or call 416-736-5312 or 416-736-2100 ext 55312. The Chemistry Department does not manually grant permission.
  • Otherwise, it may be that the priority spaces apportioned for students in your major have all been taken. The numbers used are based on previous years' distribution of majors needing the course. In that case, it may be that the distribution of priority seats needs to be adjusted. Please visit the first-year chemistry office in 102 LSB or call 416-736-5312 or 416-736-2100 ext 55312, detailing the problem. The Chemistry Department does not manually grant permission.

Do I need to repeat the labs if I'm repeating Chem 1000 or 1001?
If the course is being repeated, it is possible to be exempted from lab work if the labs were performed and passed within the previous 3 years. Then, you would be transferred into lab section 99, in which you cannot directly enroll. Please visit the CHEM 1000/1001 office in 102 LSB or call 416-736-5312 or 416-736-2100 ext 55312. Please note that the grades earned for earlier lab work will then be carried forward even if the grading of the exempted lab sessions has changed.
Do I need to repeat the labs if I'm repeating Chem 2020 or 2021?
If the course is being repeated, it is possible to be exempted from lab work if some or all labs were performed and passed. Lab section 99 is reserved for York University students repeating the class and students cannot directly enroll in that lab section. Please email mebarton@yorku.ca to explore the possibility. Please note that the grades earned for earlier lab work will then will be carried forward even if the grading of the exempted lab sessions has changed.

Students having completed lab work elsewhere should contact the Course Director about being wholly or partially exempted from the lab component.

Can I enroll into Lab 99?
Lab 99 is reserved for York University students repeating the class and direct self-enrollment into that lab section is not possible. If the course is being repeated, it is possible to be exempted from lab work if some labs were performed and passed, but this must be done by the lab coordinator.

  • For CHEM 1000/1001, please visit the CHEM 1000/1001 office in 102 LSB or call 416-736-5312 or 416-736-2100 ext 55312 or email hovig@yorku.ca.
  • For CHEM 2020/2021 or 3000/3001, contact mebarton@yorku.ca.
  • For CHEM 1500/2080/3080, contact carolynh@yorku.ca.
Why have I been de-enrolled?
There are a couple of reasons why this can happen:

  • You don't have the prerequisites and the course enforces prerequisites after enrollment. This can happen when students should be able to enroll into a course while still completing a prerequisite course but do not succeed in that prerequisite. The only way to enroll in this course is with permission from the Course Director, who is specified in the Course Timetable website.
  • Your prerequisites are transfer credits or you are an exchange student. Unfortunately, the enrollment system does not know about transfer credits or credits from a home university. To get around this, contact either the main Chemistry office (chemasst@yorku.ca) or the Undergraduate Program Director (chemupd@yorku.ca).
  • You have attempted the course at least twice before and now need permission to make another attempt. This is pretty much guaranteed but you need to convince the Undergraduate Program Director that you are serious about succeeding. You can initiate that process by clicking here.
