Students starting from August 2011:
The rules concerning extensions have changed. Since the 2011/12 intake, all new PhD students will be registered for 4 years, which is the maximum. There are no possibilities to seek extensions beyond this. This is not the same as the expected submission date, which varies from student to student dependent on their funding. You will have received a letter that clearly states your intended submission and funding end-dates to make sure you plan according to this timeline. Progress monitoring points are adjusted accordingly. Note that the Graduate School is enforcing the rule that students must submit within 4 years rigorously. Students will be withdrawn from the course if they cross this line even by a day. Exceptions to this require truly exceptional circumstances.
Please refer to the Graduate School web page for more details
