Here is one way to do the latex part. You could pass a jobname to latex. I have this \IfEndWith*{\jobname}{withsolution}{% \usepackage{todonotes} \printanswers }{\usepackage[disable]{todonotes}} in a myexam.sty file to switch between modes (with or without solutions and todo notes) and use it in the latex file with \usepackage{myexam} You could add your own latex class to org-latex-classes and add this line there. The jobname has to be passed to latex with something like -jobname withsolution if you want it to be with solutions. I use a Makefile for this purpose which calls latexmk latexmk -pdf -pdflatex="pdflatex --interaction=errorstopmode" -use-make and adds -jobname=$(basename $@) if asked to create a pdf ending with withsolution.pdf. I can send you the Makefile if you're interested. To use the jobname from within orgmode, you'll have to change org-latex-pdf-process to use the jobname if needed. I think one way to achieve this is to add a new export backend which is derived from latex (see org-export-define-derived-backend) and which sets org-latex-pdf-process accordingly (and resets it afterwards). Hope this helps. Best, Christine
