First off, we are successfully using AMC in an undergraduate course of >1000 students and both instructors and students are happier with this setup than the more pedestrian approach we used previously. Thank you very much for a great product!

Unfortunately, not all students are sufficiently careful when filling in their student number or their answers. Because of that I have added some check boxes that allow me to efficiently take off marks for sloppiness. More specifically, I defined a new command \sloppiness inspired by Alex wiki article in https://project.auto-multiple-choice.net/projects/auto-multiple-choice/wiki/Codages_simples to add 2 check boxes for TA use:

\newcommand{\sloppiness}{ %
\hfill\colorbox{lightgray}{ %
\def\AMCbeginQuestion##1##2{}\AMCnobloc\AMCquestionNumberfalse %
\begin{questionmult}{00retard}
\AMCnoCompleteMulti\AMCdontAnnotate %
\textbf{TA use:\ }\begin{reponsesperso}[o]\mauvaise{SN\ }\bareme{b=0,m=-1}\mauvaise{M}\bareme{b=0,m=-1}\end{reponsesperso} %
\end{questionmult} %
}}

With this I can efficiently take off one mark if the student number (SN) is illegible or if answers are marked badly (M).

Now, the only problem I am having is that after scanning the quizzes, all of them are tagged as 'incoherent' because none of the answers are filled in. Unfortunately, this prevents me from efficiently going through all the quizzes that have actual incoherent/inconsistent answers.

Is there a way to mark a question as not requiring an answer, so that it does not get flagged as 'incoherent' after the scan?

Any thoughts on this are much appreciated!

Unfortunately, this prevents me from efficiently going through all the quizzes that have actual incoherent/inconsistent answers.

Do you use the "i&e" setting in the manual data capture window?
"i&e" is for inconsistent and empty. If you choose "inv", you get the invalid/inconsistent questions only, so the empty sloppiness questions are skipped.
However, I agree that these questions should be skipped also for the "i&e" setting.
Maybe the questions should not be tagged as empty in this context when \AMCdontAnnotate is used. Or use another flag?
Anyway, I'm afraid that this can't be achieved with current AMC version, and needs some tuning of AMC code.

Yes, I was using the "i&e" setting in the manual data capture window. And, of course, you are right that the questions are tagged as empty and not 'incoherent'. As you suggest, I was then switching to "inv" and this worked well.

Now that I think more about this, using "inv" seems good enough in my use-case (because I generally care little about empty questions). Nevertheless, preventing some questions from getting tagged might be worth considering as a (low priority) future extension of AMC.

A related situation arises in general for a questionmult-problems with \AMCnoCompleteMulti and no correct answer. As mentioned in the documentation the system cannot distinguish now between empty and 'no correct answer'. In this case it might also be appropriate to assume the question has been answered and prevent tagging.

Thanks for the quick response.
