Chrisy08, just remember to proof-read your posts before submitting (such as remembering the apostrophe in "he's") and bear in mind that some of those who are fastidious about the English language are also fastidious about ATC standards and could very well be your future supervisors or, perhaps as importantly, interviewers.
You do give the impression of having done very little research, and while asking questions here is admittedly a valid means of doing some of that research, there are a couple of books worth reading which will tell you about ATC equipment, airspace structure and more. It'll all be useful information for future interviews, and the more you're prepared to do for yourself, the more likely you are to impress potential employers with your dedication.
I don't know what the current stats are, but it used to be the case that a qualified applicant to NATS had about a 1% chance of ending up as a valid controller. Self-funding no doubt improves the success rate somewhat, but it's still a long slog and the more you can do to help yourself and prepare yourself, the more likely you are to succeed.
Incidentally, those potential employers are don't give a damn about your standard of written English will certainly not mind it happens to be correct. Those who do care about your standard of English will most definitely give a damn if it's wrong....
