They don't have any GRE or NIU2 recommendation or paper.
I, T540,GRE2270,GPA76, EE bachelor, refused by all TOP7 CS
So if you got more than 80% GPA, forget GRE, don't waste your time.
If you need to change to CS but your undergraduate is not CS, it is very difficult!
There are nobody using Delphi here.
I like Delphi too, Delphi is much better than VB, PB.
