I imagine that there is always going to be a minority who are unhappy with something. There is always going to be some people who have bad experinces out of so many hundred.
Hope you get your problems sorted out
I am currently looking to do my ATPL ground school, CPL, IR and MCC and theese are the first bad things i have heard about Oxford. I am looking at Bournemouth and Multiflight (leeds), where you do your ground school at Bristol.
Any comments, positive ot negative would be a great help.
Cheers
