In my first attempt, I got V79 with errors spread all across and CR percentile below 40 and RC percentile below 60.
I got V83 and V84 in my previous two mocks before the second GMAT, so I expected myself to land at a similar score.
Between the two exams, I took tutoring from AakkashVerbal. I finished 7/11 sessions with him. Only 2 RC sessions and a revision and strategy session remain with him.
In the exam, I felt the questions were easier than the mocks and sort of got worried that I had marked the previous answers incorrectly. But it turns out, my reasoning skills improved, not that the level of questions got any easier.
The only mistakes came from an Evaluate Except CR question, which turned out to be experimental, and a 3-question RC passage, which, in hindsight, feels like I didn't understand.
This is because it took me 3.1, 0.5, and 0.9 minutes to get the first short passage correct; 3.4, 1, and 1.4 minutes to get the second short passage correct; and 2.9, 1.7, 1.6, and 0.9 minutes to get the fourth passage correct (which was a long one and had too many wordy options too).
It took me 2.7, 2, and 1.7 minutes to do the questions of the incorrect passage. The moral of the story is that if you take more time and understand the passage completely, you no longer need to read it again while viewing the questions or looking at the options.
It happened with my other passages but not with this one. In my incorrect passage, I had to look back at the passage from time to time, and I still got all the answers wrong.
For CR, I was able to eliminate all four options in one go in all but two questions. The two questions which took me more than 2.5 minutes to solve, I eliminated all five options and had to rework my way to the correct answer. This process gives you better accuracy than choosing the method of selection.
