I took Linear with Schrader and I enjoyed it very much. He not only knows the material (obviously) but he explains everything clearly and with much detail. There are a ton of proofs in Linear Algebra but all of them are broken down in class – you can always refer to the book for further review. I found the first midterm to be the easiest and close to what he gave as a practice midterm. Midterm 2 and the final were not really as close to what he gave as practice exams in my opinion. The Math help room, of course, is amazing if you are stuck. Also, Schrader's office hours were beneficial and he does take the time to make sure you understand whatever concept you are struggling with.
