[QUOTE="Simon Bridge, post: 5543413, member: 367532"] See how adding checking can lead to increased confidence? A student sitting an exam can be expected to remember things like worked examples made during the course - this gives them a shortcut not available to someone approaching from outside the course. When the exam is quite old, there is an additional complication that what students were expected to know as a matter of rote may have changed. I had trouble with a high-school level geometry exam once: it took minutes to work through some problems the students of the day would have done in seconds because they would have spent time memorizing which equations and formulae to use while I had to derive them. In this case I don't know what the course was so maybe students are expected to make some approximation that would not occur to us? However, I think you have good reason to be confident in your results: your reasoning is sound and the assumptions supported. I don't think anyone can, scientifically, say more. [/QUOTE]
