The chances are, you don't want to +include questions that have been previously set for, say, the last +three years. That is, you don't want to select questions the +students may already have seen. As from version 3.03, you can now do +this. + +The \sty{probsoln} package defaults to the UK academic year, which +starts in September. If this isn't appropriate, you can change it +using: +\begin{definition}[\DescribeMacro{\SetStartMonth}] +\cs{SetStartMonth}\marg{n} +\end{definition} +where \meta{n} is the number of the month. (1 = January, 2 = +February, etc.) + +The \emph{start year} is the calender year in effect when the +academic year started. For example, if this is the academic year +2011/12, then the start year is 2011. This is automatically set to +the start of the current academic year. It is also updated when +\cs{SetStartMonth} is used.\footnote{So don't use \cs{SetStartMonth} +after \cs{SetStartYear}.} If you want to set it to a specific year, +you can use: +\begin{definition}[\DescribeMacro{\SetStartYear}] +\cs{SetStartYear}\marg{year} +\end{definition} +For example: \verb|\SetStartYear{2008}| indicates the academic year +2008/9. + +There are two files concerned with previously used labels.

Note that if you want to + delete this file, first clear it using + \begin{definition}[\DescribeMacro{\ClearUsedFile}] + \cs{ClearUsedFile}\marg{file} + \end{definition} + in place of \cs{ExcludePreviousFile}\marg{file}, described below. + The argument \meta{file} is the previously used labels file + described above. \cs{ClearUsedFile} will remove all labels in + the current used labels file from the previously used labels file + and clear the current used labels file.
