Graphical depiction of complete PhD timeline, described in text below If you are unable to meet the timeline for your qualifying evaluation or general examination, you must request an extension using this petition for one advisor, this petition for co-advisors. There is no extension petition required for your final exam. Each student should consult with their faculty advisor as to the appropriate choice of coursework and timing of milestones. With your advisor's permission granted through the petition, these milestone timings can be shaped to your particular research and programmatic needs.
