How long the exam voucher is valid. Can I get the voucher before this year with 10% off. And can able to write the exam next year around March. Is it possible for me to postpond the date if i am not prepared.
I believe vouchers are (generally) good for one calendar year. You just have to schedule your exam in that time-period, and at least in the US, Prometric is fairly good - with sufficient warning - about letting you postpone it.
