Your plan seems to change EVERY day.. just look over your other posts that you have put on here over the last few days Josh.
And you said that you are currently doing your GCSE's so how come you know the grades already.. not been released yet have they?! perhaps you should be a physic not a pilot.
It looks like you want someone to say to you "yes, go that way, you will definatly be flying jets in two years if you do". The thing is, no body on here is going to be able to tell you what is the best way for you to become a pilot, there is so many differnt routes to take (and you have explored most of them on your other posts!). So whatever your next "here's my plan so far" is, there will always be pro's and con's... deal with it.
Just take the plunge mate, otherwise you will be a wannabe for the rest of your life!
