any good books? Reason for this is because my college highly recommands Linear Algebra for Calc IV, I have Calc III already, but they highly recommend Linear Algebra, so I don't want to take the risk.
I can't, because I am a High school student and I am only allowed to take one course per semester at my college.Why not just take linear algebra? Also, I'm assuming calc IV = ODE's? If this is true, most of your work will be with systems of ODE's so you'll need some basic matrix algebra. Strang's "Introduction to Linear Algebra" is not only a solid linear algebra text but really good if you want to become adept at working with matrices. Although, this is exactly why some professors have qualms with it...
yeah, I am looking into using Khanacademy too, but I still need practices.I've been using D. H. Griffel: Linear Algebra and its Applications (Volumes 1 and 2). The Khan Academy has some great videos, including a linear algebra section:

Videos and other materials from Gilbert Strang's linear algebra course at MIT are available here:

The second of these pages of short videos by Selwyn Hollis includes a section on linear algebra that covers some key concepts:
