When it comes to writing examinations, there are two options I am considering.
The first is to write the entire exam originally (which will of course mean some well-known proofs, thereby technically not making it completely original)
The second is to use a ratio of 'original' questions and actual past paper questions.
My students have access to perhaps 50 past papers to practise from.
The theory I had behind using actual past paper questions was to encourage them to do more past papers. Perhaps not for the best of reasons (as I presume they'll be hoping that they'll get lucky and get a question in my exam that they've seen already) but motives aside, they may complete a larger volume of past papers.
I'd like to hear some thoughts regarding this. Is this a good idea, is this a terrible idea? I can imagine that a few students may get lucky but in terms of the majority of the cohort (around 60), it may boost overall past paper attempts.
