It was mentioned to me in an IM that the previous year they'd asked for BBBCC at Scottish Higher, which would have been 295 points. It now works out as fewer points, but better performance in each individual exam. It can't all be down to points, though. 4 A grades is 320 points, whereas 5 B grades is 325. Which is better? You could probably argue for either, although realistically if any student was likely to get four A grades, the school would be likely to push them to do five anyway. Anyway, I'm going off on a tangent...
As far as training is concerned, haven't started yet! Still, only a few weeks away. Think perhaps the first OAA group might have just started? Can't say about CTC. I'm working my way through a 'Spanish for beginners' course on the iPad!
