Just completed the top-up at Kingston. Ghengis is correct, it's very different from the B1/2 path especially the maths. There are 4 modules to complete, Aerospace Tech (pure maths), a group project, individual project and airline economics. It takes a minimum of two years, but you can leave it over 5 years. Beware of the price, they've put a huge price rise in last year so make sure it's something you really want to do as it's not cheap. PM me if you want any more details.
