I have taken the GMAT twice now, once in June and once today. The test in June was a really bad decision as I had just graduated and involved in an internship etc. so I could not study for it and got a whopping 370. I then decided to prepare more and started to do the 60 day prep course. I completed the course but felt that I had still some problems to I re-did the math section and started to work on problems from Beat The GMAT Practice as well. I felt prepared (better than last time obviously) and took the exam today. I got a 470, which I consider a fail again. I studied almost every day since I started my new internship and have studied at least for 2-4 hrs every night after work and on the week-ends. I don't know what to do anymore. Can someone please help me out and tell me what I need to do to at least crack 650 or so?

Thanks
