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
(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
a. The sub question 1 ?
b. The sub question 2 ?

\documentclasscommand, 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.
