Thanks for the replies!
I actually do take flying and my PPL serously, so I will make sure that the instructor and flying school know it.
I will try to find out what they think in school about me going to flying school during my work experience, before actually trying to arrange something with flying school or going to see what it's like there.
What do you mean by saying 'don't pay in blocks'? Do you mean that I should have some money on me everytime when I go flying and that I should pay only for what I am doing right now?
And yes I know that I should have some more money than the actual training cost, just in case if something goes wrong or if I need some more time. So, if the training costs £7000, how much more money should I have just in case?
Thanks
