Yes I did the multi choice at an independent computer centre & the oral & practical was done at an independent maintenance facility at FW airfield.
Fact was ACME briefed you on exactly what(very,very easy)tasks to expect.
I took mine alongside a Philipino who worked in Saudi Arabia.He couldn't read a micrometer to save his life.
When he left he still couldn't,but he had an A & P ticket.
I'm not having a go at ACME,I got what I wanted out of them.
They didn't exactly enhance the reputation of the A&P certificate around the world though.
