No-one has answered you heliporto, so I'll chip in. The UK CAA removed the interim procedure for new starts at the end of November 08, a move which I think was ill advised and badly handled. They have given us no guidance on whether or not you may still apply your exam credits gained under the interim procedure to the fixed wing exams, and I asked them specifically about this in December. I understand they are shortly to issue an AIC or some similar guidance on this topic, the best advice I can give you is to hang on for a week or so and see what happens.
