When you choose biochemistry

At the end of Year 2 — you enter the BMSc program and its module in Year 3.

What to watch for

Biochemistry is a BMSc module you enter in YEAR 3, not first year — Western calls BMSc a 'second-entry' program. ESM gives assured Year-3 entry if you finish Year-2 core courses with at least an 80% average and no mark below 60%; from Science (ES) you take the same first two years but must compete for Year-3 seats through the competitive pool. ESM requires ENG4U, MCV4U, SBI4U and SCH4U (SPH4U recommended) and its average guideline runs above Science's. If you would rather stay in Science, note the Honours Specialization in Biochemistry and Chemistry (Chemistry) and the Honours Specialization in Genetics and Biochemistry (Biology) are separate ES routes into the subject.

The same application also gets you to

Medical Sciences is the entry point for 3 other majors at Western. You are not choosing between these at application time.
