I loved this professor! His lectures are easy to follow, and the course itself is pretty straight-forward. It takes a lot of studying and practice, but that's what you get when you're taking multivariable calculus. If you are interested in math, he is a great professor to talk to and listen to. He is a really chill, friendly professor who is always available to help, and always explains everything crystal clear. He once stayed in office hours during finals week for an extra 2 hours or so just to go over some key concepts and chat about math and any other questions we came up with. Really great professor, and I think if you put the time in, you'll learn a lot too.

Sheehan is a good professor, his office hours are very useful and he is really good at explaining the material. It's also refreshing not to have a professor with an accent. However, I got a 5 on the BC Calc exam, and that being said, I got a C+ in this class. I understood all of the material but the tests were extremely hard, or would have a couple problems that really took a lot of intelligence to get even partial credit on. On my second midterm, I studied my ass off and I knew the material really well. I ended up getting full credit on all of the problems, except one, and they were all 20 pts, so I got a 78 on the midterm. His grading policy isn't lenient and the class is usually filled with Asian geniuses that set the curve at 100%. Only take this class if you are naturally brilliant or OK with getting a C when you work your ass off.

If you take Brendan Sheehan, you're gonna have to master the homework and quizzes. I didnt, which was why I failed his two midterms, and dropped the class last quarter. But I am currently taking 32A with Radko, and I am at the top of my class.
Sheehan's class is filled with Asian geniuses who destroy the curve, so dont count on the curve to save you.
However, his midterms are hard but his finals are extremely easy. One of my friends got a 7% on the first midterm and passed the class at B-.
Also, his TAs suck. My TA always cheats me out of points, sometimes even half the grade!
So if you take Sheehan, you must be prepared to master the homework, and deal with a usually cocky, strict TA, and respect him/her to death (or make it look like you are)!

I took Calculus BC and Math HL in high school, so this course wasn't too hard. I started off badly though, and got an F on the midterm. By the end I pulled up my course grade to a B, but I went to all of my TA's office hours and did every example problem in the book. This course isn't impossible, you just have to work hard! Go to your TA's office hours, read the book (and do the example problems), do your homework and most importantly go to PROFESSOR SHEEHAN'S OFFICE HOURS! He is extremely helpful and on the morning of the second midterm I went to his office hours and he gave hints and explained what would later be on the midterm. Good professor, good class. Just don't fail the quizzes.
