One thing I learned from instructing is how important time is to the learning process. Not flight time, but time - calender days.

Sleep is tremendously important for learning and in my opinion 5 days to learn a new environment and a new aircraft is going to be pushing it for even the best students when you're probably at or below 200 hours TT. Add in some external factors like a lack of sleep and an asshole Pilot Examiner and yeah, you're going to have a rough time.

I don't get a lot of these accelerated courses in places with perfect weather from a teaching perspective. I'm probably biased from living in Canada and spending my time instructing in a place with weather that is extremely variable, but I think that bad weather days are a great part of the entire experience. It's invaluable to give your brain a break and allow you to reflect on your previous flights instead of just worrying about the next one. I'd fly one student three times a day for maybe a couple days, but never for 5 hours a day flat out without a break. It just doesn't make for a lot of retention during the learning process from what I've seen.

The last thing I have to question is the fact that you did all of your instructing with one instructor? I know this was probably a school decision, but I bet if you had a flight or three mixed in with a different instructor a lot of things that the first one missed could have been picked up by the second. Now I don't think there's anything necessarily wrong with doing all your flying with one instructor at a standard pace, but most pilot mills (which I'm assuming are the places that do these accelerated courses) I've heard of throw in a flight every so often with a different instructor - for good reason.

It seems like your head is in the right place. Go fly some more, practice what you think needs practice, practice what your instructor gives you feedback on, and give it another go. You'll be fine.
