"As you probably know the GRE is an adaptive test meaning that it gives you harder or easier questions based on your previous answers. This makes the questions at the beginning far more important than questions towards the end (in each section of course). So the best thing you can do is focus on the first few questions ~10 on each section and make sure you get them correct which will put you in a high bracket and give you a much better over all score. Also sign up for another test in say 2 months and study for it by taking practice tests (adaptive ones, trust me the money for online ones is worth it) so you can get your method down. Taking a second time should dramatically improve your score if you are honest with your self about what you did poorly on on the first one and learn from it for the second."
