Most doctors recommend that you wait until the first day of your missed period before taking a urine pregnancy test. This is usually about two weeks after conception. However, some tests are more sensitive than others and can be taken earlier.
Then work backwards from your earliest deadline. Build some extra time into your planning process for unexpected delays because you can only take the GRE test once per calendar month. Keep in mind that it can take as long as four weeks for your official scores to arrive at your designated schools. The GRE is offered at testing centers almost every day. Call your local center for details and to book your test. While in theory you could sign up for the GRE with only two days' notice, don't depend upon this luxury. Call at least one month prior to your desired test date.
