I'm trying to work in another exam by the end of the year when a particular TTT voucher expires, but I've also got work deadlines and family stuff and travel, lol. Do the voucher deadlines mean you have to use the voucher to purchase the exam by that date, or do the voucher deadlines mean you have to take the exam by that date? I want to make sure I get this voucher worked into my schedule without losing it, you know? Thanks!
