New to ACCAPayment for Exemptions

Hi everyone, I have just started on my ACCA journey!! I am hoping to register for the standard entry session in Dec 22. I will be eligible for 3 exemptions but I am just wondering about the fees. I can see on ACCA site it says that you have to have paid up all your fees before sitting an exam, does this mean I will need to pay for my three exemptions before I will be able to book into the exam session? I have summarised what I think the fees would be, just looking to see if anyone can confirm? Fees: Initial Registration - £89 December 2022 standard entry - £143 (does this cover one exam and then additional exams cost a further £143?) Three Applied Knowledge exemptions - £98 x 3 = £294 Total = £526 Ideally, I would like to be able to pay my registration, then book into the Dec 22 session before the end of October and then pay my exemptions at a later date but not sure if this will work out! Thanks Yvonne
