rinasharma,
Do not forget to know the 1000 high frequency word list by heart. These are the words marked with a sold circle or square in Barron's 3500 list. Do not miss a single word coz they arent many. Most of the first 10 questions will contain words with this level of difficulty and/or frequency. If u dare to go for 3500, do yrself a favor and warm up yr word-talent  with very popular Latin n Greek word roots. I know it doesn't sound easy but with hard work and persistence it will look easier. Take as many PowerPrep tests as u can since that will be a real reflection of yr actual GRE score. My average score of 8 tests was only 10 less than my final score.
Try reading the passages faster and learn to scan sentences rather than reading word by word. RC is the area where most Nepalese mess up. On my first practice test, I had got only 2 right but I believe I only made 2 mistakes in the real test. It gets easier, trust me!
Try to give due importance to the first 7/8 questions. You will be weighed heavily on them...u must know it by now.
Good luck and let us know if it helped.
