Does anyone have any experience of these? My son, Y8, has been put forward by his school for these. At a local university, it's going to involve 6 Saturday mornings next year ... he isn't exactly full of enthusiasm 
. I don't think I would be at his age, either.
Can anyone sell them to me/him? He's got a great ability in maths - last year got Silver/Distinction in the UKMT Junior Olympiad - but, alas, doesn't have a great passion for the subject. Just seems able to do it easily. Would be more interested in computer programming-type applications of Maths - which I suspect might be part of this series of talks.
... but to give up six Saturday mornings to go to Maths lectures ....
