CEGEP Science Profile Prerequisites for Quebec Engineering and Medicine Programs
By Muntasir • Published Nov 13, 2025 • Updated Sep 27, 2026 • Admissions & Applications, Canadian Universities & Colleges
Engineering and medicine at Quebec universities both expect a completed DEC in Sciences de la nature, or the specific math, chemistry, physics and biology courses that program covers. Missing one course, especially biology for medicine, closes the door even with a strong R score.
🎓 Sciences de la nature is the standard préuniversitaire profile behind both engineering and medicine admission
📩 Core courses cover calculus, linear algebra, general and organic chemistry, mechanics, electricity and magnetism, and biology
🏠 Most engineering programs need the math, chemistry, and physics blocks but not biology
🎓 Medicine programs need the full profile, biology included, since it feeds directly into first-year coursework
The Profile Behind Both Paths
Quebec engineering and medicine programs both draw their applicants overwhelmingly from one préuniversitaire profile: Sciences de la nature. This two-year DEC pairs general education courses with a fixed block of math and science courses designed to prepare you for the first year of a science-based bachelor's or professional program. Choosing this profile in CEGEP keeps both engineering and medicine open as options through your final application. Choosing a different profile closes one or both doors before you even apply.
What the Sciences de la Nature Block Covers
The profile builds around four subject blocks.
Mathematics: differential calculus, integral calculus, and linear algebra
Chemistry: general chemistry and two terms of organic chemistry
Physics: mechanics, electricity and magnetism, and waves with modern physics
Biology: a general biology course covering cellular and molecular topics
Universities treat this block as a package, not a menu to pick from freely. A university engineering or medicine program lists Sciences de la nature, or an equivalent set of specific college courses, as a ministerial admission condition layered on top of the general Quebec secondary diploma every CEGEP program shares, a layering SRAM confirms applies program by program.
Where Engineering and Medicine Diverge
Engineering programs lean on the math and physics blocks hardest. Calculus, linear algebra, and the physics sequence show up directly in first-year engineering coursework, so a program requires them explicitly while treating the biology course as optional or unnecessary. Medicine programs need the full block, biology included, since it underpins the first-year curriculum in a way physics does not. Skipping the biology course in CEGEP because your engineering plan does not need it quietly removes medicine from your options later, even with strong grades elsewhere and even if you never expected to change your mind.
| Block | Typical engineering requirement | Typical medicine requirement |
|---|---|---|
| Calculus I and II | Required | Required |
| Linear algebra | Required | Required |
| General chemistry | Required | Required |
| Organic chemistry I and II | Sometimes required, program-dependent | Required |
| Mechanics | Required | Required |
| Electricity and magnetism | Required | Required |
| Waves and modern physics | Sometimes required | Required |
| Biology | Rarely required | Required |
Treat this as a general pattern, not a guarantee. Confirm the exact list against your specific target program, since requirements differ between universities and even between programs at the same university.
If You Are Missing a Course
Some CEGEPs let students add an individual prerequisite course outside their main profile, for example a Sciences humaines student adding a single physics or chemistry course before applying. Availability depends on the college and the specific course, and picking up a missing science course after the fact usually means an extra semester or summer term. If you already know your target program, confirm its exact course list on that university's own admissions page before you finalize your CEGEP course selection. Requirements differ slightly between engineering programs and between medicine programs.
Check Before You Choose Your Profile
Talk to your CEGEP's academic advisor before you register for your first semester, not after. Advisors confirm which Secondary 4 and 5 courses you need already completed to enter Sciences de la nature in the first place. Math and science sequences in high school build on each other, and missing a Secondary 5 prerequisite blocks the CEGEP profile you need for either career path.
