There is a great technique that lot's of test takers including myself use during the verbal section - write down all the answer choices and cross-out the one's that you think are incorrect. Somewhere on the forum I have read that on the test day, it's better to write all of those 41 verbal question choices(A,B,C,D,E) before the start of the section in order to not waste your time during the section and be fully concentrated on the questions themselves. I wonder how one can manage to do this, because during the breaks you're not allowed to sit before the computer, you should go outside. Should I make this grid before the test starts, like when they give you some time to read the terms of the test(or something like that)? I am curious about your answers.
The only time that you have for yourself where you are at the computer, with your notepad and pen and the clock is not running against you is during the 4 minute "tutorial" at the beginning of the test.
Since this tutorial comes before the AWA and then the Quantitative it is better to use this 4 minutes to write down any notes for those sections - particularly Quant. In many cases your notepad will be replaced between the Quant and the Verbal sections (whether you want it to be replaced or not) or you might even raise your hand during the Quant to have it replaced because you are out of space. In any case it is not too likely that you will have the same notepad to begin the verbal that you had at the start of the tutorial.
So you will likely have to devote time from the beginning of the verbal section if you want to make a 41-question A - E elimination grid. I think that it is better to wait and make a new grid at the beginning of each question. That is your time to cleanse your mind of the previous question. We are talking less than 5 seconds to write A - E and in that time you shift your mind from the previous question to the one that is upcoming.
That is my take on it.
