[LON-CAPA-users] Checking status of a part that has timed out

[Gerd Kortemeyer]

Hi,

A problem may be that this is apparently needed on the map-level. I think external:: only works within a problem.

Some of us from Illinois were asking about setting up a sequence so that three timed quizzes (each of which consists of a single multipart problem) could be taken in succession, each succeeding quiz becoming available only once the previous one had been attempted. I have this working now (thank you Ray for your very valuable guidance!) EXCEPT in the case where a student starts a quiz, gets distracted, and never submits a part and it times out.  Starting but never submitting an answer does not show up as a “try” -- using the otherwise successful condition:

This seems to be confirmed in the email exchange in the logs here:
