Hi there,
Please STOP using and promoting PSI certification . I`ve tried to pass magento certification by this service , which adobe recommends using here https://www.certmetrics.com/adobe/candidate/exam_scheduling.aspx?%20redir=yes
I`ve paid 125$ , followed the instruction , but after waiting for 1 hour at PSI secure browser I gave up because proctor didn`t show up!
On my requests to get refund nobody in answering , so PSI service is a scam . If you don`t believe me, please take a look in reviews

Magento have to disable opportunity to use PSI for certifications as people just waisting money on it !
