You know for a fact you're being stupid. No offence, but with your scores, as stated by the Christ's Admission Tutor in his thread, you are guaranteed an interview and compulsory pooling. Your results are fantastic and I think most people would kill for them. As for whether you will nail an offer based purely on interview, well no. Cambridge assess your entire application and give no particular weighting to any aspect of it. So, because frankly you're asking for an answer, no one can say without a doubt about who will get an offer. Even those with 98% + UMS scores can fail to get an offer and those with UMS in the high 80s can achieve one. Your relevant UMS is 95.4, don't pretend that Cambridge is out of reach for you - it isn't. All the best in your application, I hope you achieve an offer.
