# Parts of a question without parentheses in document class exam

How to do Parts number of a question without parentheses in document class exam ?

\documentclass{exam}
\begin{document}
\begin{questions}
\question
\begin{parts}
\part The sub question 1 ?
\part The sub question 2 ?
\end{parts}
\end{questions}
\end{document}


Its output will be

1. (a) The sub question 1 ?

(b) The sub question 2 ?

I need to get the same output without parenthesis for the number of sub questions like

1. a. The sub question 1 ?

b. The sub question 2 ?

• You need to show us what have done so far by giving a minimal working example starting with a \documentclass command, the packages that you are using and \begin{document}...\end{document}. The MWE should be as small as possible, compile and show how you are,doing a question without parts. – Andrew Sep 7 '16 at 10:31

Adjust the macro \partlabel:

\documentclass{exam}

\renewcommand\partlabel{\thepartno.}% Default is (\thepartno)

\begin{document}

\begin{questions}
\question The question?

\begin{parts}
\part The sub question~1?
\part The sub question~2?
\end{parts}

\end{questions}

\end{document}
