I almost cannot believe I passed the 1Z0-068 test!
I failed on July 5 as the passing score for RAC part was 66%, while these days I got a email and found the passing score has been lowered to 60%, and I passed it!
Today is my lucky day, as I got another relevant email which told me I did pass the test and I could download the eCertificate of it.
OMG, two months past and now I got it, like a dream.
