Assuming that you are using a Revision Kit form one of the ACCA approved publishers (BPP or Kaplan) as you should be doing, then there will be an answer in the book !!!

They will always send (1), they might send (2) with it if they did pay directly through the bank (as opposed to sending a cheque). They might choose to send a letter with them as well, but there is certainly no need to.
