thanks form your reply. The exams normally appear after the twenty four hours, the BA6 is available as the BA5 and BA6 can be done in any order. I rang ICB today only to find out that because this is my 3rd attempt I now have to wait six months before I can resit the BA5. I only failed in my 2nd attempt getting 84%. I am self studying so I did a mock only to find it is nothing like the real exam but doing the real exam gave me an insight into the content. I will not be waiting for 6 months to resit, I am now going back to the AAT, six months is just out of the question.
You should double check that your BA6 is available, BA5 & BA6 both became available to me as soon as I passed the BA4.
All the best for the rest of your exams.
