My initial CFI:
1. Was it sit easy to pass?
I should say, it was exhausting (see Question 2) but not extremely difficult. I'd say it depends on how good theoretical knowledge you have.
2. How long does your oral last?
Mine wasy 8-9 hours, something. Though, I've heard that that is not a normal duration in other parts of the states. However, most my friends here in San Diego had a very long oral. I've heard orals as short as 2 hours.
3. How long was your flight test lasted?
I think mine as 1,8 h long. Some maneuvers I had to demonstrate, other evaluate and correct him on.
