David is an excellent instructor. He presents information in a way that is maximally useful to the student. Instead of repeatedly pulling examples from the book as many math professors do, David presents the most general forms of a problem, and then outlines the core tools you have at your disposal to solve specific instances of the general form. He happily answers questions that students have during class, and is consistent in connecting concepts to how they might be applied in the field.

He is incredibly smart but I had a hard time following what he was doing on the board. He tends to go off subject a lot and is working on like 2-3 problems at a time (my notes looked terrible!). The TA saved my life. I got an A because of the TA.

He's a pretty decent professor. I found his lectures pretty boring, actually. He says jokes and such but I didn't find most of them very funny. His tests are very straight-forward. He even drops hints during the test.

I would suggest taking him!

I took 3C with this professor

In my opinion, he taught this class the way it should be taught in all classes: through logic. He doesn't use the traditional math book which is good because the book just uses a bunch of huge equations that have a lot of variables and symbols that look confusing. Just about everything in this class can be explained as you learn about the many ways to kill yourself or lose all of your money (aka Russian Roulette, disease problems, and poker). I came out of this class truly grasping the logical concepts of the class rather than a bunch of random and useless equations that can be explained with WORDS that people can understand. Granted, it makes it harder to help other students who have trouble in the class with different professors because you see the equation and say "um.....I don't think I even used this equation..." when in fact you used the concept of the equation without the complication of the excess variables.

So for all of the premeds, sorry. His class isn't one that you can just plug and chug equations into like with calculus. Plus, since he teaches off the top of his head and uses no notes to direct him, you need to go to lecture and take notes on EVERYTHING he writes rather than trying to study on your own with the book.

Overall, he's a genuine guy and very easy to approach. He wants a lot of students to pass so his curve is overly generous. His homework is pretty challenging but they are meant to once again focus on the concepts so that by the time of the midterm you can reason with the problem since he always adds a new factor that usually isn't discussed in class.

Take him!! It's not an "easy A" but he's thorough and super chill and an awesome professor.
