Penn State Learning in the basement of Sparks is a great place to meet students with other students taking Math 220, and you can even get instant help sometimes.

Linear algebra done right, 2nd edition is the book that made sense of Linear Algebra for me.

Jim Hefferon's Linear Algebra is a synthetic approach including many calculations for empirical experiences, as well as formalization.

A formal linear algebra approach is given in Beezer's A First Course in Linear Algebra

Gilbert Strang's Linear Algebra and its Applications is the standard senior-level engineering text on the subject, and perhaps a more valuable long-term reference then our own texts.

Strang's full course is available free online from MIT, including videos.

And of course the Khan Academy has videos.

Linear algebra toolkit is an older but very good interactive resource
