I am asking myself the same question. I am going to take my OCP exam ($25) next week and in the case of failure I still have 2-3 days till the end of promotion. (I've been already forced to reschedule the exam once due to Covid lockdown in my country. Hopefully it wouldn't happen again.)
In "Terms and Conditions" we can find a sentence:
Valid only for one exam attempt per subscription
To get the special price you have to activate the free subscription and then you are allowed to register for the exam and pay the discount price ($25). It is totally clear.
About 3 weeks ago I've seen somewhere on the Oracle website an information regarding using multiple email accounts by one user. I had the impression that this is not allowed to have several subscriptions by one user - in this case more than one $25 attempt shouldn't be possible as well. Unfortunately I haven't read it carefully enough and I cannot find the information any more.
To conclude, I really hope that I've read something wrong and getting the discount price more than once is possible... but is there any person who already got it?
I did my 1Z0-819-J on second attempt and for both attempts I paid discounted $25 price.
After failed attempt and 48 hours waiting period I was curious if I could register again for discounted price, and I was able to.
But still I thought it might be only error, so I just asked one of our oracle education sales representative assigned if I can register again for discounted price.
I was told that at beginning that discount was indeed valid only for one exam attempt, but then they wanted to be more customer centric and they allow another attempt for discounted price.
(I really don't know if this means that each attempt until 25th April will be discounted or only second one)
So I registered again (for discounted price), I succeeded (80%) and I have my certification.
@Thank you Jeanne and Scott for your books, and thank you Enthuware team for your mock exams.
Candidates may schedule a retake of a failed exam after 48 hours, for an appointment date 5 days from the failed exam appointment date.
I noticed one change, that badge is now issued through Oracle CertView and not Credly (acclaim).
I saw someone 3 weeks ago having badge still issued through Credly(acclaim) so I opened ticket to Oracle and ask them about it.
Reply was that "my badge is available for me to to access and share in CertView. It will not be available in Acclaim. You will have all the same access to download, share, and verify in CertView."
