Dude, I'm in the exact same boat. Top 5 school for UG, high GPA, good GRE, but no publications when I applied back in December (only had a year of part-time research then). I've received 3 rejections out of the 7 schools (all top 20) I've applied to already, and the rest isn't looking too good either. Not really sure what I should do now other than find a job somewhere. Seems like PhD dreams are all but over .
