When I took the GRE, my mind was a bit fried after spending the time/effort on the essays, which I believe affected my performance in the verbal/quantitative. I took the 10 minute break in between, is there anything I can do other than walk around/get water/bathroom that will help refresh me? Same goes for the 1 minute break between other sections. I was wondering if anyone had personal anecdotes or research knowledge on the issue, because I don't want to have an inaccurate reflection of performance
