I agree with seen_the_box, if you are with Bristol GS I guess you are a modular guy... anyways modular or integrated have the same problem: low hour pilots don't get the job so easy. In order to do that, you need hours and then you will be good.
For now, try to make your best, if books don't help try to get some other help around from other pilots or other books, anything that could help you to pass except for cheating do so.. Even the biggest fail sometimes
Don't get demotivated..!!
