The following LaTeX class has been prepared for Exam Papers at the Dept. of Computing at University of Surrey.
If you should want to rebuild the files, or play with the source, you need exam.dtx and exam.ins. They can be compiled using docstrip. See the LaTeX documentation.
The old version used a style file instead of a class file. This is possible with style file and template. The style and the class are supposed to be functionally equivalent.
