Well, spending night and day over the next 3 weeks might not be the best way to prepare yourself. If on an average, you're getting 37 on the Verbal score, so there's a good probability that you might even hit a 40 on the higher side. Since you do not have a lot of time left,taking a radically different approach maynot be all that helpful. What you should be doing at this point of time is that you should be focusing on smoothening the rough corners in Verbal. It is also the time when you should be reviewing all that you have done and seeing the "patterns" in questions. You might want to go through "Thursday with Ron" videos and see whether the strategy you have been using so far in different areas are correct or not .

Do you think that going through the RC99 book in the next 3 weeks will be helpful or be too much? Also, I haven't done the powerscore book. Do you think that completely doing these two books in the next 3 weeks will be counterproductive? Thank you for your advice. I will definitely check out those videos.
