I would like to postpone it as well, but I have not seen and read any info regarding to postponing from ETS website...besides, just several weeks away now , I wondered whether we still had time to do that ...(unless you need not to prepare TOFEL as well)
So my plan is to take a try in this May, and at least I will know what kind of exam it is.
Cancellation Policy
You may not change your test date or cancel your registration. If you do not take the test and do not plan to register for another test date, write "absentee credit" across the face of the admission ticket and send it to TSE Services. It must be received within 60 days after your test date.
If your request arrives before the 60-day deadline, you will receive a partial credit equivalent to U.S. $10 approximately six to eight weeks after receipt of your request, which you can use for any test. The remainder of your payment will be retained to cover expenses for processing your registration, ordering and shipping test materials, and holding space at the test center. Once you have been admitted to the test center, you are NOT eligible for any partial credit. Cash refunds are not available.
If you did not test but plan to register for a new test date, send your admission ticket (for which you will receive a credit equivalent to U.S. $10 toward the total test payment), a completed registration form, and the rest of your test payment within 60 days after your original test date to TSE Services.
For example, you would calculate your total payment as follows:
TSE Payment in U.S. Dollars:
$ 125 test payment
– $ 10 absentee credit
= $ 115
Sometimes a test center may not be able to give the test on a scheduled date. This may happen because of an unforeseen circumstance, such as non-arrival of test materials, a postal strike, a natural disaster, or a political disturbance. When a center cannot administer the test on a scheduled date, the test will be rescheduled for another date as soon as possible. If you do not wish to test on the new date, you may apply to TSE Services within 60 days of the rescheduled test date for a full refund of the test payment. Refunds are made in U.S. dollars only.
