Hi, I'm 31 and started my college course last September, I was worried I would be the oldest among loads of 16 year olds. It turned out, there is an older lady than me there, she's 36, then myself, then there is a few 20 something's and lots of 16 year olds. But I can honestly say, every one of them are lovely, I get on with then all, and the course is good. We started with 23 in our class, i think we are down to 13, loads have dropped out, but its good. don't worry, just be yourself.
