Undeclared Science (First Year Studies Only)

Undeclared Science - First Year Studies Only

Program Website:
Administered by: Faculty of Science
Program Format: First Year Studies Only

Undeclared Science is a one-year entry option that allows students time to explore foundation science courses before deciding to declare their major in one of the Biology, Chemistry or Medical Physics programs.

O.S.S.D. with six Grade 12 U/M courses, including Grade 12 U courses in: English, Advanced Functions (MHF4U), two of Biology (SBI4U) or Chemistry (SCH4U) or Physics (SPH4U).


  1. ENG4U/EAE4U is the preferred English.
  2. The grade(s) required in the subject prerequisites (normally in the range of 70 percent) will be determined subject to competition.
  3. Completion of all three science courses is recommended
  4. Subject to competition, candidates may be required to present averages/grades above the minimum.  

Students who are not yet sure about which science discipline is of interest to them enrol in this plan of study. The first and second semester curriculum is common for Biology, Chemistry or Medical Physics. All of the information provided in the plan description of these science plans is relevant and applicable to the undeclared science students.

Students in science programs must enrol in SCI 180 in their first semester of studies.

Undeclared science students must, by no later than February 2nd, declare their intention to enrol in a plan of their choice from one of Biology, Chemistry, or Medical Physics. During the course intention period, students will select applicable courses for the fall and winter terms of their second year from their chosen plan.

Depending on space availability, undeclared students who complete the curriculum of the first year with CLEAR Academic Standing, and who achieve acceptable grades in the required courses of the discipline they wish to pursue, will remain in and be enrolled in the science plan of their choice.

Students already in a declared plan who wish to switch to another science plan should contact the First Year and Common Science Office, opens in new window by February 2nd.

Any undeclared science student will continue to be enrolled in the undeclared plan of study until they achieve CLEAR Academic Standing. In cases where the undeclared designation is on-going due to poor academic performance, student course intention will be subject to a written statement of understanding between the student and the program director of his/her desired program.

Research Practicum

SCI 999 - Research Practicum gives students the chance to gain hands-on research experience, in a lab or in the field, by engaging in the research work of a faculty member. Ryerson records participation in the practicum on the student’s Official Transcript.

SCI 999 is a non-credit, pass-fail course that is not used to fulfil degree program requirements. Students who meet the expectations for the research will get a passing grade. These expectations will be worked out between the student and the professor at enrolment. To take part in SCI 999, students must have a CGPA of 2.5 or more, and they must commit to a minimum of 5 to 10 hours each week (on average) for one term.

There are no tuition fees associated with this practicum.

How to Enrol

  1. Students must first find a supervisor. Descriptions of faculty research are available on the Faculty of Science website, opens in new window.
  2. Students should contact supervisors whose research interests them by email or in person. Students must give their potential supervisor an unofficial transcript, opens in new window, a one-page resumé and a brief covering letter. This package must include their contact information, degree program and stream, a brief statement of their career goals and how this research experience would further those goals, and any relevant work experience (paid or volunteer).
  3. Follow the instructions available in the PDF fileResearch Practicum Application Form, opens in new window.

Liberal Studies

Students must take three lower level liberal studies courses and three upper level liberal studies courses to graduate. Students must not choose courses that are restricted for their program or major.

Please refer to the liberal studies chapter of this calendar for more information on the Liberal Studies Policy. Further information on liberal studies can also be found at the Faculty of Arts' Liberal Studies website, opens in new window.

Table A - Lower Level Restrictions

PCS 111, BLG 181, BMS 150, CHY 182, CHY 183 and SCI courses are not available for credit.


Students may pursue any Minor offered by Ryerson (with some exceptions). Please refer to the Minors chapter of this calendar for further information on individual Minor requirements and exclusions.
