I'm predicted A*A*A with an A* in History, received almost full marks in my History mock and came top in my year. Unfortunately though, I underperformed in my GCSEs (got 888776555), and for various reasons pulled a 6 in the final exam. This was completely unexpected because I'd gotten 9s all year, and I almost ended up not taking History A-level because it was such a shock - but I'm so glad I did because I proved that my GCSE result was what I assumed it to be - an anomaly. I love History, and want to take it further, but would it be a terrible idea to apply to top unis (UCL, KCL, Bristol, Durham) with a 6 in History? It seems so unfair, considering that some of my classmates who got 9s at GCSE are currently getting Cs and Ds. I haven't gotten anything less than an A* in months, so I'm understandably horrified by the idea that I could be rejected by the 6 I got over a year ago!! I might have extenuating circumstances, but I'm worried that they're not 'extenuating' enough...
In short; would I actually have a decent chance at somewhere like UCL/Bristol, or would it be an awful idea to apply if I did badly in the GCSE?
