R S:
For CKA, I want to know after how many days I can schedule the second attempt ? I am planning to take exam (first attempt) on 28th august but my voucher is expiring on Sept 7th. Please help. (Sorry guys just got too busy so couldn’t notice my voucher will expire 
)
unnivkn:
once you get the result of first attempt & if it didn’t go through, after 24-hours you can schedule next attempt.
Strider:
@R S Hope it won’t be needed but I would suggest schedule within 2 week of your exam and try to analyze for yourself what might have gone wrong. I faced a network issue during exam and cleared in second attempt that I took within 2 week
R S:
Sure thanks!!
