It sounds very much like there’s a UK version of TBS’ King of the Nerds coming, Objective are currently casting (click for larger):
If this is what this is, the US show was quite good fun – challenges are split to alternate weeks between science-y and creative. I’ve seen series one of it but not seen series two (but Reality Blurred who is usually bang on about this sort of thing suggests it has even better challenges than the first one). casting@objectiveproductions.com is the direct link if you want to mail for an application form.
If it’s something completely different then meh.
