I binned my first attempt at my NFT due to poor nav technique and then flew with an instructor, ex RAF who showed me the standard closing angle method and the 1-4-7 and 1-5-6 technique after that I never bothered with the constantly off track technique again and its a lot easier!
GPS etc are all good but are not totally reliable, nothing wrong with map clock compass.
No disrespect but how can you pass if you get lost on a test?
