[Edited] I am very shortly going to be sending off my PhD application. I cannot apply quite yet because I am waiting on my bachelor's documentation which was withheld (library fines which are now cleared) but now it is in processing, and I do have my transcript. I have my master's documentation. The BA uni say they don't know when the cert will be ready, it could be a week or two, or longer presumably. The deadlines for PhD applications are set as the summer, but I know that many faculties like to have the applications in sooner because they want to decide on their student quantities. Is there some kind of unspoken deadline that I should shoot for in general [e.g. late Feb, Apr etc] or does it vary by institution? Does one lessen one's chances of acceptance if applying nearer to the official early summer deadlines?
I should mention that a staff member in my choice of PhD uni has already approved my proposal and agreed to be my supervisor. Should I apply anyway without the BA cert and just say it is in processing [without going into reasons why]? I am not applying for funding.
