Ace MATH 123
McGill University
MATH 123 is McGill's flagship linear algebra course, covering matrices, vectors, systems of equations, and basic probability. It's typically taken alongside the calculus sequence (140/141) by students in STEM programs.
It can be quite intense — there's a lot of material and most of it is brand new from high school, so you have to take it seriously.
You've landed on a page designed to give you everything you need to pass your MATH 123 final.
