Do I have to write the GRE (Graduate Records Examination) Physics Subject test?
If you have not completed a degree at a Canadian university, this test is highly recommended (as of Feb 2011). International applicants must be aware that the GRE Physics Subject test is offered 3 times each year in November, December, and April. Students who wish to apply for a September admission are strongly advised to write the test in November or December of the preceding year in order to meet admission deadlines because of the likelihood of lengthy student visa application waiting times.
