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). Is it too late for USC?
In case I get an admit from USC which is better USC or NCSU? How much is the cost difference between the two?
Is the difference in terms of job opportunities really too much between USC and NCSU?
