So NCSU is good in a field that you're not interested in, you don't get enough support from the professors, and you're not happy with the atmostphere. Do you think that you can put together a decent JMP that leads to a job you want at a department like that? I know it sucks to lose a year, but if it improves the quality of your work, then it might be worth it.
What kind of job do you want? Is it more in line with placements from NCSU or placements from Pitt?
