it is very helpful and not tough through this I get a lot of help to clear my quiz exam

though not tough but helpful

They are not so good,i want some question about mathematicians like who invented what in which year?I dont’ like it

Hi – sorry you didn’t like the quiz – I think a famous mathematicians quiz is a good idea – I’ll bear it in mind

Questions are fine, but a theme for the questions may be more interesting for the students. E.g. Could you think of a question that would make, fibonacci, euclid, and pythagoras’s relevant to, for example, space travel?

Hi Ceri – thanks for your comment. All of the questions on the site are designed to be used in a pub quiz and not necessarily with students – if they have proved useful for that too I am glad. I do try to keep away from designing questions with a narrow specialism as the aim is to test general knowledge and not specifically maths.

It’s helpful and not tough. ..tnx
