Going to be doing this tomorrow. I'm thinking it will be similar to the Yosemite exam than anything.
However, if you do decide to take it online, here's some advice for you.
Do NOT take the exam until you are ready.
I can't stress that enough. I say that because when you purchase the exam and have a code to take it online, you will be given a 48-hour window to take the exam. That is how long it will be available for you to take. If you wait longer, the status of it will show as expired, and unless there was some outlying circumstance to cause it, the only way you can take it is to purchase it again. Additionally, that 48-hour window is based on date and time based on
calendar day, not business day. So if you purchase this on a Thursday at, say, 4pm local time, you will have until Saturday at 4pm local time to take the exam.
That's what happened to me, where it was purchased at 12 noon on Thursday, so I had until 12 noon on Saturday to take it. Saturday, Pearson's servers were returning 503 error codes all day (Server temporarily unavailable), which caused me to miss the window. In talking to Pearson on it they'll create a ticket for you that will take 3-5 business days to resolve. So if you have the time and patience to wait, you can go down that route. If not, you can dispute the payment with your credit card processor, get the money refunded, and purchase again.
Again, this doesn't explain why the exam has the option to be unproctored, as you can still take it at an AATC, which will be proctored. Additionally, the code that was mentioned in the thread has no bearing or outcome on the actual exam, so I do not see a reason why it would be unique to me or anyone, because it just provides the availability to take the exam without having to go to an AATC to do it. For example, if there weren't that single AATC in Auckland, the closest AATC to New Zealand would be Melbourne, AU: 3.5 hour's flight and a passport away. Doable, but you'd be burning half a day to get there, 2 hours to take a test, and another half day to get home.
With that, if you are thinking of taking it, here's what I suggest:
- Wait until you believe you are absolutely ready,
- Purchase the exam (this starts that 48-hour clock),
- Spend the first 24 hours preparing for the exam (last minute studying, practice tests, etc.),
- Take the test no later than 36 hours after purchasing it.
That way, you get at least one more day's study time prior to taking it. And again, this says absolutely nothing about not having any training/studying material (read: Apple's prep guide, any books, notes, etc.) next to you while you are taking the exam.
Either way, I'll give a better idea on how it is tomorrow, as mine is rescheduled for no later than 2 days from now (4/29/16) and I'll be taking it on 4/28.
