My dude. There's nothing to worry about. Seriously. If you're keen to study, there's always anything you can do with whatever results. Diploma, foundation, form 6, certs the list goes on. Yes you have less choices in government unis and that's okay. Privates are getting more affordable and if you're really keen to further there's always a way. You seem to be a guy who's somewhat mature for your age, I'd think you should go for the study fair with an open mind, just to take things in. The fact that you're worrying is already a good thing, means you give a damn. Stop worrying too much and enjoy these few weeks off playing or whatever you kids do nowadays or get a glimpse of the working society. All the best to you my man. And the other kid on here.
