Linear Algebra was at the core of almost every math and cs course I took. I ended up taking several semesters of it and by the end we were approaching highly relevant problems in subjects like quantum mechanics and machine learning. I cannot recommend studying it highly enough!

If anyone is interested in building an understanding of Linear Algebra from the ground up, I would suggest some of Israel Gelfand's work: http://www.scribd.com/doc/35985818/Gelfand-Lectures-on-Linea... It's not for the light hearted, but when you get through it, you will be deeply changed and have a new perspective on even basic math, such as integration.
