The drafting exercise involved writing a memo for a client (a complaint). I would advise you to read through the documents quickly and highlight any dates/notable events (cause they are usually important in setting out your reply). Make sure you have at least 30 minutes to draft the document - this is what ultimately matters. Split it into sections to make it easier to read. Avoid legal jargon if it is not a letter between two lawyers. Summarise at the end and what you want. If you have done the LPC, it should be easier for you. I hadn't at the time I did mine though, so no stress. Best of luck!
