Dear friend, I appeared in nav atpl on 22nd feb attempt, got 61 marks which is quite frustrating, I had studied from Oxford and Keith Williams, I am not sure where did the rest of the questions came from, questions based on mass and balance and flight principles, e.g. Questions based on stalls, cg etc. I am not sure how to go about next time rather from which book to study from along with Oxford and KW. Can you guide me on that please. Would appreciate.
