Did you apply for uni this year? Let us know if you'd like some help deciding on what to do next, or you can PM me if you want to discuss privately.
I got CDD two years ago, was put into Clearing, called about 30 universities in and around London, was offered 4 courses in total (some relevant, some very random), accepted a place at a uni ranked below 100, got a 2.1 in first year, transferred into Year 2 at a mid tier university ranked in the 60s, in a much nicer location with students who have the same academic abilities as me, and where I'm much happier.
You haven't failed and there's always another option. Let us know if we can help!
