Hi Alison,
Sorry again for being slow - work has been overwhelming lately (as too often, indeed) - and thank you for offering your help. I have played a little bit with the challenge interface and it seems straightforward. However, I am wondering if it makes more sense to make the entire bio101a as one challenge, or have smaller challenges (e.g. one for each unit) that could be combined in a working group or a course. What do you think?
Anyway, I have started to put together a list of possible questions/exercises from which we can pick to make a challenge. Maybe you can add to it, comment what's already there, highlight whatever may seem more suitable for a challenge, etc? I will start again working on this document by the end of this week, so we can make a test run with unit 1 (hopefully) soon...
Thanks again for your help!
Best,
Sebastien
