Not too easy. Not too difficult.
It is well organized, easy to learn from, and fun to read. Topics are relevant, courses are so much easier and engaging than reading a textbook alone and the fees are totally reasonable compared to what you get in return.
I really liked (blushing) the narrator's voice.....it did not make me fall asleep! Even at 1 am. while catching up on study after work. Also the graphics are awesome. I noticed I can retain what I learn, while learning from textbook I can only retain a fraction.

Advice for students:
Don't underestimate the course. They make it easy to retain the info, but it's up to you to take advantage of what's given just like everything else in life. I found having a deck of 3 different colored sets of index cards to be more helpful than I thought. You will see why. And it helps to listen to the lesson at night as you get ready for bed, clean up your room, or even as you lie in bed resting....you can retain what you hear. My learning style is spatial, not audio, but I found that I learn faster and retain better when I combine both.
