Pretty easy, overall.
Math 20D is a very interesting course because of all the real-life applications that are derived from it. Dragos Oprea was an excellent instructor, who made this course much more interesting than I originally thought it was going to be.
The midterms were very straight forward, but do not feel too confident without going over all of the material. The final was one of the biggest highlights because of its difficulty and the need to actually know what you are doing. I learned a lot about real life applications and a variety of fields that differential equations can go.

Advice for students:
To succeed, make sure you understand the concepts as you go through the course. Do not be scared to ask around if you forgot something from a previous course. This course felt much better with the help of friends and knowing that you can go to office hours to talk to the professor.
