It wasn't too bad. I took a prep course through GSU. You might want to look into it, a lot of the students in the course were prospective GSU applicants.
https://robinson.gsu.edu/executive/execed/programs/gmat/index.htmlDr. Cohen provides his own text and teaches a lot of tips and tricks. He recommended taking the test 2 weeks after the course ends but suggest you take extra time, unless your practice exam scores are close to your desired score.
I did very well on verbal and got a 6 on AWA but my quant score was dissapointing. I did much better on practice exams than the actual exam.
