Welcome to the School of Gods

Olly Morris, (mostly) normal kid, is living his (mostly) normal life when a Messenger to the Mighty Gods summons him to Gods School. There, Olly's given a grumpy 'mobile gnome' named Jeff, told by immensely powerful and scatterbrained teachers he must pass a life-threatening exam - Or Else, and plunged into a class of unfriendly godlings. With no powers, no idea why he's been chosen and a growing sense that nobody actually knows what's going on, Olly can't work out if this is the best or worst school in the universe.
