I think it would be great if the students can force the assessment to save the questions. At Netacad site the questions were saved when passing throgh the pages, in here we don't know when the page is saved.
This is causing:
- Loosing answers or revisions when getting internal errors.
- Loosing answers when disconnecting.

It could be a good idea to add a Save button somewhere or at least show when was the last save.

Cheers!
