I have Admits from ASU(Computer Enginneering), Colorado Boulder (Professional Embedded Systems), NCSU (Computer Engineering)
More or less decided on NCSU.
Decision pending from USC (Applied on Jan 15). By what time can I expect the decision. And if I get an admit from USC(Computer Engineering)
which will be better USC or NCSU?
