Great, thanks for the suggestions! Though it seems really hard to make the difficulty of the alternative courses match the original ones closely enough, e.g. your strength requirement is much easier than the current one, endurance is much harder, social is easier...

Creativity: "5 drawings" is too vague for someone who doesn't know how to draw (how much is one drawing?), but writing 500 words in one sitting is a great idea and I'm taking it!

Games: I like the suggestion, and would prefer to start with just chess. No idea how much work is reasonable to ask from a beginner, though.

Altruism: icks me out :-)
