Thank you for your email. You were declined an offer of admission to the PhD program in CE not CS (Computer Science) that is a different department.
There was a very strong and large number of applicants this year and as it is a very competitive admission process with a printed set of minimums that are required. Only those applicants were considered for admission offers that met or exceeded those printed requirements.. .и
Therefore, the committee was and will not be able to offer you admission to the PhD in CE in the ECE Department.
