Matthew, I personally didn't find it too bad or demanding, but that also depends on a few things like going to class and reading the textbook. There were also quite a few "Free Marks" given and those were always nice. If you find the study of aging boring, it's not going to be "easy".
I wrote a review on it a few months back if you're interested in more details.
