This morning, ISC 2 sent the number, and I set up an appointment.
My thought had been, "even though I want a few more weeks prep, I'll get the voucher now and just arrange a date at the FAR end of the bracket--"
Whoops ! I hadn't paid attention to ISC 2 posting 5- to 7-workday processing right on their site--I was inviting disaster:
Supply and demand among us test takers: When you don't have your voucher id yet, you might see your optimal test dates disappear. Especially if a group all buys the promo and descends upon the same test center, LOL
The gist, for fellow test takers: Buy a near-dated promo voucher only when you're ready for the exam itself.
