New to ACCARegistering for exams before confirmed a student

Hello everyone, I want to sit for December exams, however I have not started my registration yet. I head that after the online application is completed it can take up to 5-7 working days to be confirmed as a ACCA student and for the exemptions to be awarded. But the last day for the standard entry for December exams is on 31st October. So I was wondering if we can register for the F5 and F7 exams before being a confirmed student and before the exemptions are awarded. I know I will be exempted from F1-F4 papers. So will I be able to register with the account I'll get immediately upon online application? Regards, Akash M
