Hi, I've got an interview with NAT's on Monday and i just thought i'd ask for some help, as most of the people on here seem to be pretty clever and helpful

I have visited two airfields, but at one someone suggested my age could be a problem for me. I'm only 18 and my A levels are starting tuesday, and i was wondering if anyone else had been in a similar situation to me and if anyone had any ideas on how i could use my age as an advantage.
Thank you for your time
Matt
