Unlikely, but depends on how desperate sixth-forms and colleges are about filling their places. Ask yourself - With a 6- 5, how likely is it that your going to get a A*- B in A level Science Conversely im sure if you work hard and have conversations with your teachers, they may squeeze you in. I'd give you a 35- 40% chance of you being accepted into any science. But have a try and hopefully you'll get accepted. Good luck! NOTE - Bio and Chem are really HARD,don't get me started on physics! You've got to have the brains!
