Often I have homework with just a few graded exercises. I like to TeX my homework in just one file and to hide the exercises that will not be graded such that I can hand in my graded exercises with the corresponding points.
So I like to have a option like "answers", but then for "graded exercises". Is this possible?
Example
I have this:
And I want an option to only show this:
Manually using conditionals
\documentclass[addpoints]{exam}
%\newcommand*{\SHOWUNGRADED}{} % uncomment to show ungraded exercises
\begin{document}
\begin{questions}
\question[10]
Why is there air?
\ifdefined\SHOWUNGRADED
\question Compute $\displaystyle\int_0^1 x^2 \, dx$.
% \else % uncomment to keep question numbering (part, subpart similarly)
% \stepcounter{question} % uncomment too, to keep numbering
\fi
\question[15]
How much wood would a woodchuck chuck if a woodchuck could chuck
wood?
\end{questions}
\end{document}
It would be nice to get this automatically done for questions, parts and so on, however I could not find a predefined solution in the documentation.
