Fully agree with all the previous advice, learn the systems, not just the answers. Once you really know the subject you have the confidence to answer any question no matter how it's wrapped up. I work alongside a guy who failed the ATPLs twice and was given an extension to pass them on the third time over a 3 year period, now that's making it hard for yourself, but as i said he works in the same job for the same salary and the employer doesn't care how long it took him to get the exams passed.
