Thanks...am gonna try to study all weekendIf you are going to request a new date then be prepared for a possible delay to your entire application. I am not sure the "holidays" or a "mid-life" crisis would constitute a significant reason for a date change. The test is not that hard, there are plenty of online resources to help you practice the tests and the actual test seemed easier when you actually sit it. If becoming a Canadian Citizen is important, work through it, there will never be a good time for the test to be honest.
Good luck!
