I found that he was quite helpful in terms of answering your questions. With the class being after class though, it was somewhat not so great in terms of not being allowed to eat.
Hated how he had arranged seating orders and you couldn't move. Other than that I found the lessons slightly boring that everything stuck easily in my head (over 90% was easy even not paying attention
I graduated about 10 years ago, it doesn't sound like Mr. Lund has changed all that much ;) He didn't engage the class a whole lot, but he did teach clearly defined lessons and helped you if u asked
His class is great to sleep and play game in my Ti-83plus. His exam has SO MUCH mistakes and it took me hours to explain to this old brain.no food in class :(
