# Auto assign points/marks to Multiple Choice Questions

I am creating an exam with both multiple choice questions and structured questions. How do i automatically assign one mark or one point to multiple choice questions so that when i compile the paper the total number of marks includes that of multiple choice questions.

if i use this code, i get the following

\documentclass[12pt,addpoints,answers]{exam}
\begin{document}

This exam has \numquestions\ questions, for a total of \numpoints\  points.
\begin{questions}
\question What is the function of nucleoli?
\begin{choices}
\choice the formation and breakdown of the nuclear envelope
\choice the formation of centromeres
\choice the formation of ribosomes
\choice the organisation of the spindle during nuclear division
\end{choices}
\question An actively growing cell is supplied with radioactive amino acids.\\
Which cell component would first show an increase in radioactivity? \\
\begin{oneparchoices}
\choice Golgi body
\choice mitochondrion
\choice nucleus
\choice rough endoplasmic reticulum
\end{oneparchoices}
\question \begin{parts}
\part There are 20 units of DNA in a cell during stage G2 of mitosis. Give the number of units of DNA   you would expect to find in this cell
\begin{subparts}
\subpart[1] at prophase of mitosis; \fillwithdottedlines{0.25in}
\end{subparts}
\end{parts}
\end{questions}
\end{document}


I modified \question to default to 1 point, so you have to use \question[0] to assign points by parts. I couldn't find an option to suppress printing points, so I used \pointformat to create one.
