Good luck! I did well (98% UMS) at the old spec and I'd say make all writings and speakings as original as possible (don't be afraid to make jokes, or go a little off-piste), use loads of idioms and revise especially key verbs and negative structures (as a lot of people hear the 'ne' before a verb in a listening and assume it means no, when actally what comes after could mean only or hardly.
