Course Registration

print out of course listing


Students enrol in courses and manage their course timetable (add/drop/view courses) via the Student Web Service (ACORN). As a University of Toronto graduate student, you will also use ROSI to view/update your personal information, view final grades/academic transcript and your financial account. Transcripts as well as convocation tickets are also ordered through ACORN/ROSI.

While academic advisors, faculty and staff are available to assist and advise, it is ultimately the student's responsibility to keep personal and academic information up to date at all times and to follow all University, SGS, departmental and program regulations, requirements and deadlines. The student web service makes it easier for students to check and correct this information. If questions arise about requirements, policies and procedures, students are responsible for seeking answers for these questions from staff and advisors.

IMPORTANT: Medical Biophysics and other university offices may send important information to you by email. Please ensure that your email/mailing/permanent address and telephone numbers are up to date at all times. Under University policy, students are required to maintain a University based email account (i.e., ending in or, record it in ACORN/ROSI, and regularly check for messages. That account may be forwarded to another personal account but it is the University account to which the University will send official correspondence. New students are advised to validate their UTORID at the University Library early. The UTORID provides access not only to the email account but also to QUERCUS, the University’s student portal and learning management system. Many courses use the portal to provide online materials, discussion groups, quizzes etc. It is also used by the University and various student groups to make important announcements and administer elections.

Please note: You are considered officially registered as soon as you have paid tuition and incidental fees, or have requested to register without payment.


Use of the Student Web Service (SWS) to enrol in courses means that you agree to abide by all of the academic and non-academic rules and regulations of the University, the School of Graduate Studies and graduate unit in which you are registered, and assume the obligation to pay academic and incidental fees according to the policies and requirements of the University of Toronto. You normally use the SWS to add or cancel courses. If, for extraordinary reasons, you are unable to use the SWS contact your graduate unit as soon as possible. Users of the Student Web Service are expected to be responsible when using the SWS and should not attempt to flood the system with requests, or to automate the process of course enrolment. Such activity may clog the system so that other students may be denied access or experience degraded performance. Any student(s) attempting such activity may be denied access to the SWS until after the relevant registration period.

Personal Identification Number (PIN)

Students must log into the SWS using their student number and a personal identification number (PIN). The first time the student logs in, this will be derived from their date of birth (format YYYYMMDD). However, at that point the student will be required to change the PIN. Subsequent access to the system will require this new number which should be known only to the student. The student number and PIN together constitute an "electronic signature". Never give your PIN or student number to someone else.

Forgotten PIN numbers can be reset by the MBP Office. To avoid having to contact the office in person or having to wait for office hours, students can enter answers to a set of questions on the SWS. When they first access the ROSI, the SWS will prompt students to choose three questions from a list. If at a later date the student forgets the PIN, it can be reset online if two of the three questions are answered correctly.

Updating & Checking Personal Information

Students may view or update their address, telephone number or email address through the Student Web Service. When entering new information, the "add" option should be used. "Change" should only be used to correct information in an otherwise correct record (e.g. typos).

Students can also check other personal information (immigration status, title etc). As immigration status affects fees, all students are advised to check this information at the beginning of each year.

Request to Register Without Payment (Deferrals)

For graduate funding commitments
Students who are receiving funding as part of the Medical Biophysics’s graduate funding commitment may request to register without payment online. 

For OSAP, CSL and US student Loan recipients
Students who have received notification of an award through the Ontario Student Assistance Program for their U of T program may make their fees arrangements through the ACORN up to the registration deadline instead of having to appear at SGS, if the amount of the loan covers the minimum payment and no outstanding fees are owing.  The online arrangements may also be available for recipients of Canada Student Loans and some US government loans.  Please see the Office of Student Accounts website for details.

Requesting Courses

To enroll in courses, you must request your courses on ROSI. Students who do not register (pay or defer fees) by the registration deadline will be removed from their courses. Courses such as RST9999Y and the seminar course, MBP1015Y (M.Sc. students only) are preloaded and requests are not necessary. Please check ROSI to ensure that you are enrolled in these two courses.

Some hints for enrolling via the Student Web Service (ROSI)

  • Section code: F (Fall session), S (Winter session or second term) or Y (full year course)
  • Teaching method is LEC (lecture).
  • Meeting section refers to the lecture code. Most graduate courses have only one meeting section, eg. LEC0101.

Late course enrolment: Students who have missed the course enrolment deadline must complete the Course Add/Drop Form and have it signed by the graduate and course coordinators.

Courses From Outside the Department

To enrol in any graduate and undergraduate level courses outside of MBP, you will need to complete the Course Add/Drop Form. You are required to submit the form to our department once you have obtained the approval from your supervisor and the required signatures from the graduate coordinator and the graduate coordinator/chair from the other department. Once you are approved, you may request the course through ROSI.

Waiting Lists

Some courses or meeting sections have waiting lists.  If the department offering the course has opted to allow a waitlist and either your enrolment category in the course or the course itself is full you can choose to join a waiting list.  If sufficient space is opened in your enrolment category, ROSI will automatically place you in the course.  It is your responsibility to check the SWS to check on your status.  The SWS will inform you of your place on the waiting list and how many spaces are allotted for your category.  You may “wait” in multiple meeting sections but if you are enrolled in one meeting section you may not simultaneously wait for another.  Your unit may set a limit on the number of waitlisted course in your requests.  One day before the final date to enrol in courses all waiting lists will be suspended and normal enrolment procedures will apply.  Consult your own unit to find out if you are permitted to join waiting lists.  Consult the unit offering the course to see if a waiting list is being used.

Checking Course Status

Students are responsible for checking the status of their course requests on ROSI/ACORN.

Status definitions:

  • REQ: Course requested. Must be resolved/approved by the last date to add a course.
  • INT: Course requested pending instructor approval in addition to approval of graduate coordinator/advisor
  • APP: Request approved. Student is enrolled in course.
  • REF: Request denied. Student is not enrolled and may not make another request for this course via the web during this session.
  • CAN: Course cancelled (student withdrew from course before deadline)
  • WAIT:  No room in the meeting section.  Student has been placed on a waiting list based on category and will be enrolled automatically if space comes available.
  • DWAIT:  Student has cancelled place on the waiting list or been removed.

Cancelling or Withdrawing From Courses

Students may cancel or withdraw from individual courses using ROSI by the determined deadline dates. Before doing this however, students are advised to consult with their course coordinator or departmental office.

Request for course withdrawals due to extenuating circumstances after the drop date are approved at SGS. Students will need to submit a Course Add/Drop Form to our department. If the request is not approved, students will have WDR (withdrawal) on their transcripts.

Please note that withdrawing from all your courses does not constitute a withdrawal from your program. To do so, you must complete a Program Withdrawal Form. Dropping courses prior to deadlines or withdrawing from a program without academic penalty does not guarantee a refund. Information on fee refunds and deadlines is outlined on the fees webpage.
