Any tips for this exam?

I might be muddling things with Final Accounts slightly but I'd recommend:

Understand control accounts and how they work and interact with other accounts. Particularly Payroll as that can be quite complex with how many different accounts will interact.
Accruals and Prepayments and how to use information on them to work out correct closing/opening balances.
Fixed Assets how to handle a disposal and how to represent depreciation in the accounts
Discounts it's very easy to get these muddled so make sure you're happy with which is which.

I also seem to remember that you needed to be able to find missing information from an account when you have a list of figures.

The exam itself. Stay calm if you find yourself getting stuck on a question use scrap to write down the relevant information from the question in a format you prefer, fill in what you are confident about and things might become clearer or fall into place.
