good luck aspheric, if it makes you feel any better people here are like 24 years old when they get into university; it's not like you'll be behind or something like that :P

You'll be able to do it :P

But even if you don't, at least over here, there's heaps of alternatives, which, despite what many may think, are fairly good (in fact, there's a shortage of people who enter trades instead of taking senior high school, so much that it's somewhat being encouraged).
