Not too easy. Not too difficult.
First of all my teacher was the reason I got a 5 on the AP Calculus BC test. He made sure to teach with concepts and not memorized mechanics that would just get me through the AP test. For example, he made sure to focus on proving theorems like the sandwich theorem or the power rule. This made me understand to a much greater degree when and why I would use those theorems.
The best thing about this is the fact that it has so many real world applications. With the progression of my Calc BC class, all the concepts in the physics class I was taking suddenly made complete sense. I could also understand the things I was studying in computer science for the very first time. The highlights of this course for me was definetly being able to learn rotation. Rotation I thought was the coolest aspect to integral calculus that there is. The best chapters is hands down the applications chapter of both differential and integral calculus where I learned stuff like optimization and kinematics.

Advice for students:
I think the best advice I can give a student is the math textbook is your best friends in this class. If you think that your textbook is not good enough, then you are better of buying one and learning out of that.
