Not too easy. Not too difficult.
It is an excellent introductory course for 3-dimensional calculus. Its applications range from physics (mechanics, electromagnetism, etc) to meteorology. The content is very interesting. The student begins to understand how motion is described in 3-dimensions and one can take derivatives and integrals in 3D. I enjoyed this class a lot.
I learned how to think about vectors and vector fields, how gravitational fields and electromagnetic fields work, how energy is conserved for some of these fields, how one can find the gradient and surface integral of surfaces, how one can transform coordinates from Cartesian to spherical and cylindrical, etc.

Advice for students:
Make sure you stay on top of the homework. Use online visualizations and graphics. Once you're done with the homework, do more problems to fully understand the concepts. Apply the concepts to physics problems.
