 This LaTeX2ε document class enables the production of University of Otago formatted examination papers. It handles all the fiddly layout requirements (such as printing “**TURN OVER**” at the bottom of every page except the last), and also ensures that the actual number of marks for questions in the examination add up to the expected number of marks.

+## Requirements
 
 You will need the `verbatim`, `fontenc`, `textcomp`, `lmodern`, and `pgfkeys` packages in order to use `ouexam`. These should all come standard with most TeX installations. To build the documentation and example files, you will need `graphicx`, `hyperref`, at least version 1.1 of the `listings` package, and the `pdfjam` tool.

 You can also build the examples using GUI tools such as TeXMaker, TeXShop, etc. (but see the FAQ below).

+### The number of marks for my questions are not appearing at the end of the line even though there is plenty of room for them to fit.
 
 You probably have a blank line between the end of your question text and the `\end{question}` macro that actually generates the number of marks. The line break gets processed by TeX before the number of marks is generated and effectively generates a new paragraph. Until I figure out how to stop this from happening, the workaround is to not leave blank lines between the end of the question text and the `\end{question}`.
 
-### I fixed that, but there’s still vertical space between the end of my question and the number of marks. ###
+### I fixed that, but there’s still vertical space between the end of my question and the number of marks.
 
 This is almost certainly because the question text ends with a list-based environment of some sort (including `itemize`, `enumerate`, `description`, `list`, `quote`, `quotation`, `center`, `flushleft`, and `flushright`). I’m not convinced that this can be fixed in a general way, but a workaround is to subtract a negative multiple of `\lastskip` immediately before the `\end{question}` (or whatever), e.g., `\vskip-2\lastskip`. -2 is about right if you want the marks to appear on the line following the question text, while -4.75 is about right if you want the marks to be aligned with the final line of the question text.
 
-### Why can’t I build content.tex? ###
+### Why can’t I build content.tex?
 
 `content.tex` is an include file for both `example1.tex` and `example2.tex`. It doesn’t have a `\documentclass` and you therefore *can’t* `pdflatex` it! The only input files you should be building are `example1.tex` and `example2.tex`.
+
+### How do I get rid of “(Subject to inspection by the examiners)”?
+
+Add this to the document preamble:
+
+```tex
+\makeatletter
+\def\@copiesof{Blah blah blah.}
+\makeatother
+```
+
+**Do not use the `\copiesof` macro.**
+
+### How do I change “N/A” to “NIL” (or or similar)?
+
+Add this to the document preamble, **before** you use any of `\material`, `\copiesof`, or `\otherinstructions`:
+
+```tex
+\makeatletter
+% Replace "N/A" with "NIL" to keep exams office happy :P
+\def\@NA{NIL}
+\let\@material\@NA
+\let\@copiesof\@NA
+\let\@otherinst\@NA
+\makeatother
+```
+
+You can then use `\material`, `\copiesof`, or `\otherinstructions` as required. Unused options will print as “NIL”.
