Willis is an amazing lecturer, even in the summer when the pace is ridiculously fast. He teaches linear algebra very well and is super concise and detailed which is extremely helpful. While some concepts may be conceptually difficult, he does his best to thoroughly explain concepts and always does examples as well. His tests can be hard but never unfair, I believe midterm averages were around the 88% and 85% mark, with the final around 80% or so. I highly recommend Willis because he teaches well, is fair, and as long as you put in the effort, getting an A is definitely manageable.

Willis is hands down one of the best lecturers I have had at this school so far. He explains concepts very clearly and is super engaging with some dry humor added in as a bonus. I showed up to pretty much every lecture because they are very useful. Definitely recommend as a professor. As far as exams go, I believe they are pretty fair. First midterm was extremely easy because there wasn't much covered yet, but the second midterm and final definitely step up the game. I personally got screwed over on the final. Don't think you can mess around and work slower because you have three hours. This mans' final is long as fuck. Has been the only final I have not finished on time. Now for some stats

My scores were: Midterm 1- 96% (Class average: 92%) Midterm 2-80% (Class average: 71%)
Final-75% (Class average: 71%). I got a B.

So as a good bet, you'd probably need to score over 10% above average overall to get into the A range.

Willis is a hilarious professor with really funny lectures. Tests are fine and not really difficult, but beware: the first midterm is VERY easy (it covers the absolute basics) and the second midterm gets much harder. This is because the material covered between the first and the second midterm is a lot to take in, and you either get it or you don't. I did very well on the first midterm but pretty bad on the second midterm (he doesn't let you drop a midterm like other math classes), so I studied a lot for the final and did really well on that. Overall, just make sure you spend a lot of time trying to understand the abstract concepts of the course - at one point you'll finally hit it and everything will make sense. If you walk into the midterm/final without understanding the core concepts of linear algebra, the exams will be rough.

Michael makes the hard concepts easy to understand. The tests are fair and you will easily get an A if you do all of the homework and practice test problems.

Michael Willis is a mad genius. His style of teaching is very unorthodox, so it might/might not work for everyone, but I loved it and I felt very comfortable with the material. Linear algebra isn't as easy of a subject as everyone believes because of how abstract some of the material can be, but Willis makes it work with his very casual and informal way of explaining the concepts. He makes reasonable tests and is overall a nice guy who initially comes off as a little abrasive but is actually just really eccentric and really funny. Willis made me truly interested in the material and I recommend to anyone taking this class.
