I am now at 44hrs TT, and now contemplating the upcoming skills test for PPL.
There is a belief that you have to wait to 45 hours before you can do the skills test. In fact you can take the test at any point after you have completed all the mandatory training i.e. after 35 hours flying. Not may ever do but it is an option.
The main tip is enjoy yourself and just show the examiner that you can safely operate the aircraft.
