Where do I start?
First, you don’t do formation any more and EFT is nowhere near a CPL these days.
Bad habits include flying on instruments. Poor lookout techniques. R/T of varying standards.
GOOD habits/points. Ground school often much better, tech knowledge, less prone to airsickness, preparation (when you pay for flying you prepare more).
This is generalisation. We have a way to do things, adapt to our way and life is good. Fight it and do your own thing, you are going to struggle. The system is designed to take you from zero to hero, go with the flow
