I seriously need help to improve my score.

:(
I prepared for a month and scored 450,490, and 510 in the GMATprep. I was going through the Manhattan SC for a week and OG13 practices for both quants and verbal.
GMATprep verbal score was stagnant at 14,16,18, Quants was 35,37,and 44.
I think with some preparation I can do well in quants but not sure about verbal score.
I am in India and English was my second language. I need to target a score of 700 ++ in coming three months.
Pls advice.Note : I ran out of time in both the sections and ended up guessing 8-9 question in quants and around 20 question in verbal.
