I would wait to apply. I applied 3 years ago to five different school and did not get accepted. I had a 3.2 GPA and a 284 on the GRE Q: 143 V-141 AW: 3.5
I have just recently within the last year started studying for the GRE again and have had much better results after taking it a few times. I applied for the spring 2017 admissions. I am hoping to get in now that I have brought up my GRE a good bit. I would not waste the money to apply though without at least getting a 290 on the GRE since you have a 3.0 GPA. I honestly wish someone would have told me that 3 years ago, because I wasted a lot of money trying to get in to schools I did not meet their requirements.
