all those who have been shortlisted but possess 4 years bachelor's degree should see HEC Notification

Get its print, and show them if asked about Master's degree

And if they didn't want 4 year bachelors, they wouldn't have shortlisted them in the first place.
I have been shortlisted too with BBA Honors, but I also filled the Master's row with some masters degree which I don't remember for the sake of appearance in the test and also by that time I had found that HEC equivalence notification.
