Hello,
CamilaGonzalez. I have to say that your official score is the outlier at the moment, but since you have a little over a week in which to prepare for the retake, I would suggest devoting your efforts in practice to increasing your accuracy on Easy and Medium questions, per their official categorization. If you let yourself get caught up in 700-level questions, you will likely do no more for yourself than to increase anxiety; the GMAT™ punishes mistakes more severely at these lower levels anyway. I guarantee that if you can hit 75 percent accuracy on Easy questions, 70 percent on Medium questions, get a Hard question here or there (not even 50 percent of the time), and submit answers for all questions, you will earn your target 600. You can even save time guessing by having a prearranged guess answer that you can choose each time (say, (D)). That way, you can click through and at least have an answer marked in a timely fashion. I would much rather give myself a 20 percent probability of landing upon the correct answer with little time and mental energy spent than adopt a random guessing strategy that took extra time and increased anxiety.
This week, you should review what you have worked on already. If you want to practice new questions, stick with official ones, perhaps from that question bank you mentioned, but focus on a few at a time, not large sets. You know already what the exam is like, so adding volume will not prepare you for the task at hand; studying what has caused you to go awry in the past and putting that knowledge to use on a few small sets of questions can be productive, not only in helping you increase your accuracy, but also in giving your confidence a boost, just when you will need it the most. In review, look up the questions you have missed in this forum. Take the time to read through some of the responses until it makes sense to you why the wrong answers are wrong. That is about it. Review, practice, review. Go through each category of question in this manner—PS, DS, RC, CR, SC (no need to delve too much into sub-categories)—and you can set yourself up for success in a short study window.
Finally, if you think you might draw a blank again on test day, you can practice deep breathing ahead of time. Doing so sets off a physiological response that helps you calm down, and you will be able to think more clearly. A little stress has been proven to help people perform better at mental tasks; too much stress has the opposite effect. You can even give yourself one free pass every 5 or 6 questions. Just lay eyes on the question, and if you feel that heart rate spiking, take your deep breaths, see if logic can help you in some way to eliminate
anything, and simply pick an answer. If you focus on small clusters of questions at a time, 30-36 questions start to feel not so bad.
Relax. Take your time to study. Practice some more. Your approach this week can make all the difference. And if you have questions at any point, you know how to reach out to the community.
Good luck.
