Having taken his class in person, I would like to second this. The man is a beautiful thinker and he presents linear algebra in a way that is extremely comprehensive and approachable.

His lectures helped me through my engineering degree. My lecturers made it hard to understand, Gilbert's teaching made it easy to understand.

Came here to say this. Go through the actual course methodically though - readings, summaries, problems solutions. It's incredible. Miles ahead of coursera equiv.
