if that is the case, what happened with the other tests? what change took place to cause your performance to decline?

1. your teacher. 2. your book. 3. other books.
suggestions on linear algebra books
1. steven leon's linear algebra with applications 2. gilbert strang's linear algebra 3. shaum's outline

some advice:
in the future, when this sort of thing happens where you put due time and effort into understanding mathematics but for some reason do not accomplish that, you need to head to your teacher's office. make him/her earn his/her buck.

this seems to indicate that your teacher does NOT show you examples. this may well be the main reason why you are not learning. what appears to be going on is that your teacher is filling his/her ego by emphasising on theory while failing to make it understandable/sensible through examples. not impressive.

is your teacher correcting that homework and giving you feedback?

if that is the case, then you really need not be worring about applications at this point  at least none that are beyond those a typical linear algebra book would introduce.

search for a shaum's outline or similar publication.
