SBRP2 INT vs UK

I've got a problem, i've studied P2 from SKANS (Lahore, Pakistan) nd just came to know that they teach INT variant (its always INT here usually) but Im appearing for P2 UK, its my fault that i chose UK variant as i didnt knew earlier! Could anyone guide me on what extra do i need to study for UK variant, any major differences, where should i study from, i've got only 4 days! Im appearing in P1 too this attempt, should i leave P2 nd focus on P1 as P1 exam is the day after P2 exam nd i have only 4 days left!!! Please reply soon! Thanks!=))
