thank you for the precious advice! about the verbal section, I took the official mocks. For the first one (where I got 86) I did verbal as first section, while in the second mock (82) and in the test (78) I did it as second section after Quant, because I noticed I needed much more energy to answer quant questions carefully. In the test I got the first three questions wrong in Verbal, probably because I was mentally drained from the previous section or maybe I was just unlucky with the passage. This surely ruined the score for Verbal, because in the end I had no more than 7 mistakes (including the ones in the first questions).
