Good morning and thanks for the shout-out,
akshay9126.

As you may know, I am always down for a good ESR (Enhanced Score Report) discussion.
First of all, congrats on the amazing perfect Q51 score!
As for the Verbal section: you are correct that you answered one question incorrectly in the first quarter, zero questions incorrectly in the 2nd quarter, 2 questions incorrectly in the 3rd quarter, and 3 questions incorrectly in the final quarter — for a total of only 6 wrong out of 30 counted questions (80% accuracy).
As others have already noted, you also appeared to be rushing in the final quarter of questions, where you only spent 1:05 per question (you have an average of 1 minute, 48 seconds per Verbal question).
Based on my extensive ESR research, a score of V36 (80%) with only 6 counted questions wrong is unusually low. For example, I have seen a score of V40 (90%) with 10 wrong:

On the other hand, it might make you feel better to know that I have also seen scores as low as V35 (75%) with only 5 questions wrong:

So, thanks for sharing. Your Verbal ESR is indeed fascinating to me: it provides further evidence that Quant is much more "front-loaded" than Verbal, in terms of the first 10-12 questions having the strongest effect on your score.
Even though you performed very well on the first half of Verbal (only one wrong!), something about the adaptive Verbal scoring algorithm must have penalized you more than most. You must have made an error on an easy Verbal question at some point, and/or answered 2-3 consecutive Verbal questions incorrectly toward the end of the exam, possibly due to your pacing.
On your next attempt, try going a little faster through the first three quarters, so that you can finish the section strongly and avoid the penalty for getting an easy question wrong.
I wouldn't overreact to the question-type percentiles for RC/CR/SC in terms of evaluating your strengths and weaknesses, either — since an ESR provides a very small sample size of questions from which to generate this data. Yes, 2/3 of your overall errors were on SC, and that's definitely worth noting, but it's also possible that this particular exam served you mostly hard SC questions, and that a mistake on an easy RC or CR question somewhere along the line was in fact the real problem.
If you're looking for some encouragement, then you definitely got a little unlucky as far as the overall numbers go! Thus, it's time for you to dust yourself off and schedule a retake ASAP. Rest assured that
most of the time, 5-6 questions wrong is enough to secure a score of V40+.
Overall, your ESR provides strong evidence that leveraging the GMAT adaptive scoring algorithm — which takes into consideration the difficulty rating of each question — still matters to your score, even on Verbal.
So, what's the main lesson here? Unlike Quant, where you can
stumble to the finish line and still earn a solid score, securing a 40+ score on the GMAT Verbal section requires that you finish as strongly as you start.
