My gut says that is not a problem. Since you are grading it in the customresponse,
you just ignore those parts of the array if they do contain useful information.
They will be saved as part of the “submission” record for the student, but that shouldn’t
be a problem.

The code in the customresponse section is relatively short and straightforward, so I just used an array to load the values. Someone at last year’s conference suggested this approach, and it works well, creating an array of the appropriate size for the submission:
