I talked at HEC to Mr. Jamshaid. He told me few things that I am summarizing it as under:
1) there are approx 400 seats.
2) 100 candidates under engineering have been informed.
3) Social Science (included Bus-Admin) candidates will be intimated after Eid.
4) The late is due to the fact that all Admissions are closed right now so there is no benefit for student rather candidates will create problems for HEC by posing queries.

So my request to all is to stay Calm and Pray to Allah. And (Bus-admin/Social Sciences candidates should) abandon all hopes to get admission this year.
