Apology accepted Jack....No hard feelings

In reply to DB6 my instructor gave me duff advice.
At no stage of my groundschool was Radio Nav
covered, nor for that matter was Radio Nav covered
on my 4 Nav exercises. I was told that I was ready to take the paper. I was also told beforehand that
the paper consisted of 20 questions and would take
1 hour. Needless to say I was a bit shocked when I saw
questions 20-25. I felt like getting up and letting the
examiner know that I was stumped. It all turned out OK in the
end. I had a word with the CFI who set my Nav paper regarding
my lack of Radio Nav knowledge. Needless to say things
are afoot to rectify the situation.
