check AMCbeginQuestion and \AMCnumero in the documentation.

\def\AMCbeginQuestion#1#2{\par\noindent}

Maybe \QuestionIndicative is also interesting in your case.

Thanks for your quick reply, \AMCnumero worked a treat!

Using

\def\AMCbeginQuestion#1#2{\par\noindent}

works well for changing the question style for ALL of the questions. However, is it possible to change the question presentation style on a per-question basis? I'd like to have my "Gender: Male Female" question un-numbered but the following questions numbered.

I have discovered that it is not possible to include two AMCbeginQuestion statements in my source file (i.e. to change the style back again), but is there another way?

It should be possible to redifine this macro several times. You can also make a local change redifining the macro inside a {...} construct. However, be careful to double the #'s inside the \onecopy command:

\onecopy{10}{

...

{\def\AMCbeginQuestion##1##2{\par\noindent}
 \begin{question}{gender}
   ...
 \end{question}
}

...

}

Please post a minimal working source code showing your problem if you need some more help.

This works perfectly. I was missing the second # inside the \onecopy command.

Many thanks. N (Great software, by the way!)
