Almost forgot...
...you can't do the RT practical exam at OFT - they don't provide the facility. When I was there people were complaining because they thought they couldn't complete the PPL at OFT as they hadn't done the RT practical with them. This isn't correct. I came home and got my PPL certificate and then a few weeks later sat the RT practical and got my RT licence - but I did have to pay to do the practical exam (£20 I think).
