I originally put these work-sheets together when I was working at a University, as a Royal Literary Fund Consultant.
I found that many of the students coming to see me had the same problems.
Most of these problems -- such as the correct use of apostrophes -- were of the kind that make the eyes glaze over when explained.
So I thought that an archive of help-sheets, which could be consulted online at any time, would be of the most help.
If anyone finds them useful, then I'm delighted.
