CPL
I luckily got through mine first time but only just.All went well until the circuit section,i knew it was the last stage of the test and what id done 'til that point had been fine so the pressure was on! The actual shape of my first circuit was anything but correct,didnt allow for winds and turned/descended at the wrong place so i was short and v high on final.When he realised how wrong i'd got it he asked me to go around and try again which luckily went fine.
Contrary to the scare stories, the examiners i've come across have seemed very fair and understanding of the huge pressure and nerves involved,and seem to take it into account.
On a side note, i know of 2 people that failed on the same basic thing.At the end of the nav they were asked to track a vor, both guys got there to's and from's mixed up and failed that section.I would consider both to be above average students but it shows what a lack of concentration does to your confidence and your wallet!
