Linear algebra is an intermediary course, that you have to take to bridge from intro calculus to the more interesting and useful mathematics like partial differential equations and statistics and probability. I agree with the above GH'ers who said Linear Algebra is totally formulaic and logical. The concepts are not difficult from an intellectual perspective, and it really can be mastered in about 3-4 weeks. But it's better to master it in the first 3-4 weeks, and not wait until the last 3-4 weeks of the semester, or even worse, don't wait until the last 48 hours of the semester. You can do this however, if you are like me, but you're going to need to be tutored by a mathematical genius like my college room-mate: Vernon Lin. I dunno if 'ol Vern is still out there, but if he is, he can prolly teach you a whole semester of linear algebra in about 8 hours. I think he became a doctor or something.
