UCL definitely want 3 A Levels taken in one sitting. If you don't do that they reject you which is a little unfair if your college makes you do a module or two early and you didn't have that information. Also a little unfair that from 2012 they require a MFL at GCSE when some students don't have that opportunity due to ****** schools ie. me and they don't know that not having a MFL will stop them from being able to apply to UCL because who the hell checks University prospectuses in Year 9?
