Nah, I'm not a professional advisor or anything like that! I'm just an average person who struggled just like most people on the GMAT journey. Thanks for the complement, though.
Your preparation overall was excellent. You used the right material and practice tests, as well as commited yourself fully. It really is a shame that the verbal score doesn't show your true potential. You are definitely capable of a higher score.
The first thing to do is take a week or two off from the GMAT. And that means a complete break. Don't even visit this website. After that, you will feel a bit better and can think more clearly and objectively. If you accept your score and feel more or less at peace with it, then it's perfectly fine to simply move on. However, if you truly feel that you can do better and that you're not satisfied, then one more attempt might be in order.
One problem, as I hinted at before, was that you didn't properly train for the actual test itself. You had the concepts down for sure, but all those little imperfections during the CAT sessions add up. Lack of mental stamina and concentration were probably the main culprits during the actual test for you.
If you do choose to retake, it's probably best to keep the preparation somewhat short. Otherwise, you risk a complete burnout. Your math skills are essentially complete, so you just want to maintain that level. The
GMATClub tests are good for that. For verbal, it gets a bit tricky. I would re-read the Manhattan verbal books to make sure that all the concepts are fully covered (this time, though, skip the end-of-chapter questions to save time and energy). There's not much left for you in terms of question practice. LSAT questions for LR (GMAT CR) and especially RC willl help, so practice with those. For SC, I'm not sure. There's the
Brutal SC document, but that doesn't have that many questions and it mostly just frustrates people due to its difficulty. We don't know how you performed on the AWA, so just review Chinesburned's
post for now.
In terms of test practice, you finished most of them. Try to find two (at most) new CAT's and use those toward the end of your study. And make sure to get the most value out of these! That means taking the test at computer desk, wearing outside clothes (no undershirt and pajamas with no shoes). Do the AWA essays and take the whole time to work on stamina. Take the breaks, but don't go overtime. Use a healthy energy source (almonds, gatorade, etc.) during the break. During this time, go to the bathroom, splash cold water on your face, and maybe stretch a little. Here's a
list of the CAT's to choose from. Also, check out the links directly below in my signature space. Most of those links cover the information in this post in much more detail and should help you.
And whatever you choose, I wish you good luck!
