Multiple page answer sheets should not be a problem, except if you need to use the photocopy mode, where subjects and anwser sheets are going to be photocopied before the exam. Can you describe the problem you face?

It seems like I am looking for the same as this person: http://project.auto-multiple-choice.net/boards/2/topics/1415

It would be much easier if I had solution sheets for each question sheet. I do not understand the workaround suggested in this thread though. If I cannot easily get the solution sheet, I will have to do it manually by hand.

So you can add indivanswers to package options, and then copile the LaTeX source outside AMC :

\usepackage[indivanswers]{automultiplechoice}

Hi Alexis,
I have the same "issue" : since I have multiple combination of my exams, I would be interested by obtaining all solutions in a single pdf file, and not only the solution of the first exam.
I tried to include this package into AMC, but I get the error: "1 errors during LaTeX compiling (question sheet)
LaTeX Error: Option clash for package automultiplechoice."
Do you have an advice in order to obtain whole solutions of exams?
Best
