Hey all,
I just got back from taking the GMAT a second time and scored a 770! Q50 V45. I posted on this forum about a month ago after I took the GMAT for the 1st time and scored a 720 (Q46 V44) asking if I should retake since I had scored much higher on practices. Even though I knew 720 was a good score, I was concerned about my quant percentile and knew I had gotten flustered and underperformed on the real exam. In this post I'll give a few words of advice to those who are considering retaking and then briefly outline how I prepared.
When I posted on this forum to ask for advice about retaking, a few users criticized me pretty harshly for even considering it. My advice to people who have taken the exam and feel they underperformed (if it was more than a few points) is to retake the exam if they have the time and the money (Even if you got in the low 700s the first time). For one, I think mentally it is difficult to feel like you "choked" on an exam and not retake it if the chance is there. Also, just taking the exam in the real setting a second time made a huge difference for me. I knew what to expect in terms of the environment, the procedures, etc. which made me way more comfortable and allowed me to relax. Instead of getting nervous and flustered when I got stuck on a problem and saw the clock ticking, I stayed calm and continued calculating or made an educated guess. I'm not advocating retaking the test if you got a 740 and had gotten 760s on practices, but if you truly feel you significantly underperformed, I think it is worth a retake.
In general, the key to my preparation was the use of the Number Properties
MGMAT book, the Advanced Quant
MGMAT book, and the
MGMAT CATs. By doing all the
MGMAT CATs and all the probems in the Advanced Quant book, I felt like every problem I saw on the real GMAT I had seen a version of before. This allowed me to quickly figure out a good approach to answering the problem. Obviously, like everyone says, Number Properties is invaluable in learning how to answer a lot of GMAT problems. I'm not naturally fantastic at math, but knowing the information in the book allowed me to answer pretty difficult problems fairly quickly. For verbal, I didn't really do any prep other than taking practice exams. For me, the sentence correction book just confusing and didn't help at all. I had done some LSAT prep which I think helped a lot.
I can finally get rid of all my prep books and forget about the GMAT forever. This forum is a great resource and I can credit it for at least a 20-30 point boost on my exam!
