Thanks everyone. Looks likes I'm about average.
Kolossi, I reckon I'm just a little behind you. I too have done three exams. Havn't done any solo nav yet but I'm actually very comfortable with the nav so I my instructor is probably taking the view that he wants me to focus on stuff where I'm weak - like PFLs. That's the thing that I perceive as the next hurdle.
Otherwise, the emphasis seems to be on refining stuff that I can do.
I was thinking that I should have done some cross-country nav by now, but I guess it's only a few hours off. I'm guessing 60-65 hours to finish.
