I know the pain you are going through - I failed every Area written exam first time around a few years ago and just scraped through some of the resits.
I just could not get the verbatim answers flowing! I thought I knew it the night before after spending hours talking to myself and writing them down again and again...at least you only had to resit the questions that you failed! However I did ok in oral boards and managed to accrue just one partly in my time there so maybe it balanced out in the end!
In addition to agreeing with the above advice is to not panic in the exam, and make sure you read the questions twice.
