%   A suitable documentclass line is the following.
%   Change this to [final] for the final version.
%   This option enables showing solutions, showing comments, and a few
%   other adjustments which seem useful at draft time.  The [final]
%   option turns all of these off.
\documentclass[stix2,uprightpi]{exam-n}

%   Include a local .clo file like this:
%\documentclass[myclass]{exam-n}
%
%   Choose different font sets:
%\documentclass[stix2]{exam-n}
%\documentclass[mtpro2]{exam-n}
%\documentclass[mtpro2,sansserif]{exam-n}
%
%   There are some alternatives for those who need special versions
%   with large fonts:
%\documentclass[largefont]{exam-n}
%\documentclass[hugefont,sansserif]{exam-n}
%
%   It wouldn't make sense for this file, but the files being included
%   using \includequestion should start with:
%\documentclass[compose]{exam-n}
%
%   For discussion of these various class options, and more, see the
%   guexam.pdf documentation.
%
%   Note:
%
%     * Several of the questions are gibberish.
%     * This collection of questions has in part turned into an
%       informal regression test for the class file.  Thus they
%       shouldn't necessarily be regarded as canonically best practice.

% Include a default category for \partmarks
