You have missed the boat for deadline applications though it's still possible to go to university in 2015 through a process called Clearing (via UCAS). Essentially, any slots that are free will be up for grabs: this might happen if people change their minds about going to university, if conditionals didn't meet their targets, or if the spaces simply aren't filled.
The downside is heavily subscribed courses like Medicine will be very difficult to get into via Clearing.
