And now for the biggest elephant in the room:
Make sure you spend a decent amount of those 50 hours practicing NDB holds and approaches as well as doing PBN and ILS, localiser, VOR etc...
Find out what is expected from the EASA/CAA examiner in your local area and practise.
Just because you CAN get 50 hours and go straight into the EASA IR test with no training it doesn't mean you'll pass it!
