bila, what can I say other than the fact that hundreds do exactly this each month! It actually falls into place very nicely. You don't have to do 8 and then 6. In fact I've done 8, 3 and aim to do another 3 in October. You are limited in how many times you can make a "booking". A booking can be 12 exams or just 1. You are allowed up to 6 "bookings" therefore it's plain to see, doing it 1 by 1 you will run out of bookings!
