No a Mac isn't essential - I was just making a point!
I use both a Mac and PC, but I found going through college and uni, they they tend to favour/teach on the Mac Platform.
Regarding being 21 - don't worry!! I was 21 at the start of my course too. Ovbiously it won't be the same everywhere, but I was one of the youngest on my course! Our ages ranged from 18 college leaver right through to a 60+ year old with 2 previous degrees. Regardless of age, you'll all (or should have) a love for design, so will have common bond already. I don't think age is neither an advantage or disadvantage. It's the work, the folio thats important.
God you can tell I talk for England haha!
