After doing the AFT practice exams I found I had seen most of the questions, so when i went into the exams I just knew the answers, went through and answered them from memory and double checked the ones I was a little suss about.
(Note: it doesn't matter how many times I look up the carriage of life jackets/radts etc, i still can't answer that question correctly, it is VERY poorly written an all of the answers are correct)
