Beat The GMAT a GMAT & MBA community

I am a MS in Biotechnology. I have been preparing for GMAT since a year. I have to improve my score.
I am not able to understand where I am wrong. I took GMAT twice and both the time I got 560. My recent practice tests after the first GMAT are

GMAT PREP . 640 (48Q/28V)

At this point I prepared a lot on SC part. I have studied from Manhattan SC and did some practice using Kaplan verbal workboook. After this I was working in Manhattan practice tests.

Manhattan GMAT 1 670(47Q/34V)
Manhattan GMAT 2 660(44Q/37V)
Manhattan GMAT 3 670(45Q/37V)

Even in GMAT magoosh, I am better, I have 100% on easy problems, 85% on medium and 79% on hard problems.

seeing these good scores, I took GMAT and again I scored 560 (40Q/27V)

I live in Houston, TX, can any one suggest me a tutor. I am aiming at 650 and above. I am an international from India.

Thanks in advance
