Hi msperlin. I've been trying your code, and was wondering if it is possible to use it for questions with more than one correct answer (for examen true or false questions). Thank you

Hi Em-Fi,

This is an old project. I'm not even using it anymore.
Have a look at package exams. If offers everything you need, including TRUE/FALSE questions.

May be a late answer. If you are interested in looking for the answer, the answer is "YES". But, there is a small bug in the definition while printing the answer key. If you use the following in preamble to redefine the same, you would get what is desired.

\makeatletter
\renewcommand{\exam@ShortKeyChoice}[2][]{%
	\if#1!%
	\ifOneCorrectAnswerAlreadyGiven
	, (\alph{choice})
	\else
	\exam@MultipleChoiceShortKeyPrefix
	(\alph{choice})%
	\OneCorrectAnswerAlreadyGiventrue
	\fi
	\fi
	\stepcounter{choice}%
	\ignorespaces}
\makeatother
