Funnilly enough, I am grading an exam written in org-mode right now. I use the exam class from the ctan archives and set org-latex-classes to have an entry that looks like this:
("exam" "\\documentclass[12pt, addpoints, answers]{exam}"
("\\begin{questions}%%%s" "\\end{questions}" "\\begin{questions}%%%s" "\\end{questions}")
("\\begin{question}%%%s" "\\end{question}" "\\begin{question*}%%%s" "\\end{question*}")
("\\begin{parts}%%%s" "\\end{parts}" "\\begin{parts}%%%s" "\\end{parts}")
("\\begin{part}[%s]" "\\end{part}" "\\begin{part*}[%s]" "\\end{part*}")
("\\begin{solution}[%s]" "\\end{solution}" "\\begin{solution}[%s]" "\\end{solution}"))
After some latex header stuff, the structure looks like this where the first question has three parts worth 6, 7 and 7 points.
* Questions
** First question
text of first question
*** Rubric :noexport:
*** parts
**** 6
text of first part
**** 7
text of second part
**** 7
text of third part
** second question
[...]
I can send a copy of the orgfile or the produced pdf to any interested parties. (It seems like maybe attaching files of any size to an email to this list is maybe not good etiquette, but I am a first time poster, so what do I know?)
If anyone else does something like this, but knows what they are doing and thus does it better, I'd love to hear about it.
