Not too easy. Not too difficult.
This course is extremely helpful when it comes to understanding why you've been learning algebra and calculus for your entire life. You can start to see how derivatives and integrals apply to real life, and how math has helped the progression of our society. However, depending on how much effort you put in and your professor, this class can suck.
I learned exactly what you would've expected in calculus 3. It's pretty much just calculus 1 and 2 but in three dimensions. There is a surprising amount of material that isn't really related to 2-D calculus, but for the most part it is similar.

Advice for students:
Depending on your professor, it isn't really that necessary to go to lectures. All the lectures are posted online so make sure to watch them if you miss class. Also you can find the answers to all the quizzes at your professors door.
