I will give you all the low down of my situation.
I have applied for a PhD in PDEs at Oxford University, and I have had my interview, and I am now awaiting response, which will apparently arrive in march. I'm not sure if my interview went well as it was not grilling at all, they just asked me about my interests and why I was applying to Oxford in particular. It all flowed well, and it was exactly 25 minutes (which is how long they said it would be). I've read around and heard that it's a good sign if the interview over runs. One of my friends has just been interviewed, and they really grilled him, his interview was an hour and twenty minutes.
But then again his application was very informal and he has lower grades, so I don't know if they were just testing him extra.
Also I am applying straight from BSc (in mathematics at the University of Sussex), but it is a 4 year PhD so it effectively has a masters combined into it (although you don't get the title).
My grades are good, in my second year I got 88% overall, and I have just received my 3rd year January results, and I averaged 91.25% over 4 modules: 83% measure theory, 87% PDEs, 96% Ring theory, 99% advanced numerical analysis. (Bsc grade for me is weighted at 40% for 2nd year and 60% for 3rd year).
Also I have done some of my own research over the summer through the junior research associate scheme at sussex
I just really wanted to know what my chances of acceptance are as I am so anxious about it.
So if you have taken the time to read this (which I really appreciate) any advice would be great!!!
