What should I call the "list of answers" a student gives in a test? [closed]

Solution 1:

Responses, where a response is "an answer or reply, or something in the nature of an answer or reply", may serve. Or choices, or replies.

Solution 2:

Submission may work for you, but may be too general.

A reasonably common phrase in university examinations would be "Present your scripts to the invigilator at the front of the hall when you are finished." I'd question however whether this would make sense for your purposes, as the word would tend to indicate hand-written copy.

It may be appropriate for you to simply use the plural: "click the button below to submit your answers."
