Hi Rocky
Just a quick final one. I'm sure that there must be local colleges in your area that will run part-time A-Level courses. Do a small search on the net, you should come up with something. Alternatively, go and speak with someone at your old college, i'm sure they will help you, or know of someone who can.
On a personal level, when I left Uni, I worked with an airline in Ops, and got promoted quite quickly.When I was 23, I was taking home approx GBP 45,000. A lot of green when you're 23 - new car, etc...etc.
I left it all to persue a career in aviation, & really haven't looked back. Sometimes you got to sacrifice a good thing if you want to succeeed. Reading your posts tells me that you want this quite bad - so go & get it. If you need any help, PM me, i'd be happy to assist.
Good luck mate, & hope you make the right choices.
