I failed my cat c 3 times and told myself 4th would be my last pass or fail, luckily I passed it once I had a long heart to heart with MYSELF. Ask for feedback from the examiner as it makes a HUGE difference. Once I examined my own faults (which were merely nerves and nothing to do with my driving) I passed it with 2 minors and passed class 1 first time with 1 minor. I know it’s easy said than done but try and keep focused and positive and remain calm. Good luck mate
