Linear Algebra took me 2 classes to learn. Haha. The first time I took it, it was so bad for the class, the teacher didn't even give back the last two tests. When I took it in my masters program it came to me. Maybe I'll post some proofs from notes. Haha.
Sometimes the teacher makes the difference on your grade and perception of the subject.
I have mixed views on linear algebra. My first course on linear algebra was an intro course so it was easy for me. Linear Algebra Two was bad for me as it was more theoretical. I was somewhat bad in that.
When it comes to computational linear algebra, I'm okay at it. I like the computing side of linear algebra better than the abstract side of it.
I feel like the computation LA is easy. Haha. Introduced to it in 9th grade algebra two. Carried me through the first test, got 100. Again the 2nd and 3rd were bad, all theoretical!
