Ey oop my honest answer is finish school.. do your a levels .. either at school or college .Then hop onto uni , get a degree ( sandwich placement) finish uni ( it's worth aiming for a good degree mark on two counts
1) you get abetter sandwich placement
2) you get a better job at the end
er.. finish degree, have a shave, wash, grovel to the bank manger for more money, find a half decent job . Then stay there for the experience for a while, learn what you can, go on EVERY course you can. Then at suitable moment .. quit!
enter the big wide world proper , with all your new skills and become a consultant for huge wedges of dosh .. live happily ever after ..
Or just hone your code skills become brilliant and hawk yourself about and get more experienced and more money ..DB is right there is no substitute for experience , you will need as much as you can to get the big bucks , the qualis just give you a foot in the door.. The voice of experience has spoken!..lol
