My advice is get into NATS and enjoy. If you fancy doing flying for leisure, then fab! But it will be a good few years down the line as you won't get much pay until you are a valid ATCO, and even then it's not until you've been with the company 3 years (ie 3 years after starting at college) until you are on proper ATCO payscales. If you do start the flying later, and want to change to it permanantly then fine. I do know of people who have done that. In short... Convince yourself that you want to be an ATCO, and put that across to the interviewers if you get to stage 3! Get through college and get posted, then you can start planning your life.....
