Computer Science — B.Sc. (Physical, Earth, Math & Computer Sciences group)
Published R score thresholds
This university does not publish an R score threshold for this program: the decision rests on your file and the prerequisites below.
Prerequisites
Basis of admission
- DEC (Quebec CEGEP applicants)
Eligible DECs and their conditions
- Natural Sciences DEC, or Science, Letters and Arts DEC, or Computer Science and Mathematics DEC (eligible for all undergraduate programs according to McGill)
Required prerequisite courses
- Mathematics: Differential Calculus (NYA, 00UN), Integral Calculus (NYB, 00UP), Linear Algebra (NYC, 00UQ)
- Two science courses among: Biology NYA (00UK) and General Biology II (00XU); Chemistry NYA (00UL), NYB (00UM), organic (00XV); Physics NYA (00UR), NYB (00US), NYC (00UT)
Official 2026 CEGEP prerequisite grid, “Physical, Earth, Math & Computer Sciences” group: acceptance possible with a minimum of 4 prerequisites, including Differential Calculus AND Integral Calculus, plus two science prerequisites; missing courses are added to the program at McGill. Very competitive program: it is recommended to have all or almost all prerequisites before entry. No minimum R score per program published on the official pages consulted: McGill's assessment uses the overall R score and the average R score of the prerequisites.
