My total score is 316. I am confused whether I should consider retaking GRE or just be content with what I got? I am confident that I can improve my Quant score from 164 to 168 or ,if luck permits, even to 170. How do I improve my verbal score? I am a non-native. I learned nearly a thousand words for GRE. I have been reading nytimes almost everyday. When I used the free ETS test I got a score of 147 in verbal (before I started my preparation, so basically after all the preparation I improved my score by 5 points only).What else can be done to achieve a score of 160? If I do decide to retake, I can do so in next 21-22 days only? Is it even possible for someone like me to improve this much in such a short time? Am I running after a mirage ?
Another problem that I face is that my eyes become extremely tired and start to zone in and out of focus. I wonder if this happens to anyone else?
