Linear algebra is great. It wasn't required for my major, but it really should've been. Definitely check out Salman Khan's videos [0], I found the KhanAcademy selection for linear algebra to be especially helpful. I took a grad course titled "Axiomatic Linear Algebra" and even at that level, the videos were helpful.
