Having just been reading some of the mark sheets for my final year project, I have come across an interesting mark scheme. I had naively assumed the mark which I received would be somewhere in the range 0-100% (inclusive). While this is true, I have found it is impossible to score outside of the (again inclusive) range 15-95%. And there was I thinking that daft marking procedures were left behind at school to be replaced by sensible people at university. Apparently not.
