Academic programs at McGill are normally four-year, 120-credit programs. In the B.Sc., B.A. and B.A.&Sc. degrees, this is split into a 30-credit freshman program and a three-year, 90-credit departmental program.
Students entering directly from high schools (outside of Quebec) usually start with the 30-credit freshman program, whereas students coming from Quebec CEGEP programs are usually granted 30 credits at the time of admission and they start directly into the 90-credit departmental program.

If you are a high school student, then you will need to consider which courses to take in your freshman year to best prepare you for a Computer Science or Software Engineering Major.
There is a separate freshman program for each degree, as specified at:
