I struggled to find a potential supervisor in London because I have a somewhat multidisciplinary research interest and I was told it was very specialist. My undergrad was in cognitive neuroscience and I did very well, being awarded the department prize. The thing is I'm not interested in the clinical/medical side at all and my final year BSc research project was on high cognitive ability. The only postgrad course I felt really fit my interests at all was the differential psychology masters in Edinburgh, but I cannot afford to live away from home.
I decided to just try and get onto a PhD and wrote my own proposal, and sent it to my former BSc project supervisor, as my research proposal is a continuation of that project. She and I met up for a chat in October, together with a possible external secondary supervisor to help with one of the aspects in which she is not expert. They liked my proposal but wanted me to work on it some more, which I did. It ended up being a bit more of a full rewrite than I'd envisaged, but I thought it was a far stronger proposal than my original submission.
Incidentally, because I proposed the project myself, I'm unfunded and currently working part time in a completely unrelated line of business.
In the meantime, the admissions office moved my start date to January, which is frustrating as I've already been working on my literature review, just without being formally enrolled yet. The admissions office received my resubmission, as I checked with them what exactly I was supposed to do for a re-submit, but I haven't heard from the academics, whom I emailed with the reworked proposal. Now I doubt anything is likely to even be looked at until the new year.
How long do these things usually take to get processed and an offer made when a revised proposal has been requested?
