Need some advice for Linear algebra

scsig805

Alright so Calculus seemed to come relatively easy to me. I was able to get good grades without much struggle. However now my linear algebra class is killing me. I feel like I am understand the text and lectures fairly thoroulghy and even feel like Im able to understand most hw problems. However when a test comes along I have no Idea how to solve half of the questions. The text I am using is Strang 6th ed and I am also watching his lectures online. Did anyone else have similar struggles in this class in particular? What could you recomend to perhaps get a different perspective on this class. Or is their any problem solving skills you could recomend? Im spending about twice as much time on this class as I am on all my other classes combined. And Im constantly in with the proffessor. So any help would be greatly appreciated.
