Not too easy. Not too difficult.
I would recommend Math 247 as a course for individuals interested in learning about math in different dimensions. While taking this course, I was amazed that although we cannot image what the fifth dimension would look like, we can still solve fifth dimension math problems.
One highlight of the course was the concept of vector spaces. Not only did I learn that math can exist in multiple dimensions, I learned how to map between such spaces.

Advice for students:
Study! The first time I was introduced to multiple dimensions in math my brain hurt a little. However, I gave the information time to sink in and tried to open my mind to the idea that not everything that happens in math can be visualized. But if students stick to it, the course becomes a fascinating window into the nature of math existing in different dimensions.
