Thanks for all the replies , just when I start the lesson with the instructor he watches my every move , even the most smallest things like where to put the checklist when finished with it , he watches and comments. I feel very under pressure when I'm with him almost as if he's waiting for me to mess up so that he can comment on it . I can honestly say I'm a good pilot when I'm at the controls I'm not nervous I'm relatively confident and for such a gap between lessons I'm not that rusty . It's just simple things like basic mathematical sums in my head i have difficulty with, I've always been fearful with maths and I always tried to not let it bother me with my flying , but if an instructor is commenting about it after each lesson you tend to louse confidence in your self .
