Sorry you didn't pass your checkride. I had mine in February, one of the first things the examiner told me was that he has no leeway on approaches, the FAA wants them correct the first time, no redo if you mess up, the ride gets terminated. He also told me he can't instruct, he said that he will be busy taking notes, that if I screwed up, just fix it and keep flying, shake it off and continue. In other words, don't look for affirmation from him, if he says nothing, keep flying. He said he was required to tell me if the checkride was failed when it happened, and that I would have the option to continue to other tasks to get them completed or stop. As others have pointed out, you should not make larger than a 90 degree turn to start an approach, you had at least a 120 degree turn, ATC would never start you on an approach like that, nor should you ever allow them to do this with you. You should have started at Dryden and flown the arc. You said that you are flying with a G1000, which should make flying the arc a piece of cake. Then you need to remember, when you get on the final approach course, that you need to fly the approach using the VOR, not the GPS, so you change the CDI to the vor, as you said. I suspect that your CFII brought you to that VOR from a position that made the turn onto course less than 90 degrees. You need to catch this during your brief. It's your ride, when you are told what to do, take your time and prep for it. You should have a picture in your head of what you are going to do before you accept clearance to start the approach, this includes which direction you are going to turn on a procedure turn. In others words, ask for delay vectors if you need them. If he told you that you had to fly to the VOR and make that turn, you should have refused. I suspect he just told to you fly the full approach, leaving it up to you to pick the IAF. Again, from that direction, fly the arc. It sounds like you got a little flustered, a thorough brief will help with that. Remember, you are PIC, not the dpe, act accordingly and don't be bullied. Fly the approaches correctly, not how you think the dpe wants you to fly it. Question him if it is not clear, or he is asking you to do something that doesn't make sense.
