I'm going thru a 141 program affiliated with a college. Next semester I will be taking my instrument courses. I plan on doing a lot of self study since I learn better that way than by sitting in a formal ground school class (I still have to take the ground school). My checkride for Private Pilot was scheduled for yesterday but the DPE cancelled and rescheduled for two weeks from now. My instructors keep telling me that my knowledge is better than the average private pilot candidate and I feel like I am very prepared for my oral when I get to take it. Should I go ahead and start studying for instrument now or should I wait until after my checkride?
