Hi there,
According to my knowledge, as you will clear your backlogs, your percentile will automatically increase. Furthermore if you wish to choose CS branch for your Masters you should have 75% in your B.Tech/B.E and a score of 315 or more in GRE if you want a renowned college. Still, you can aim for a good score in TOEFL so as to cover up the rest.
Good luck.

Hi,
GMAT is the preferred choice to get into the top B-Schools outside India. However, other than a strong resume, you should have at least 2-3 years of work experience. And if you don't have work experience, you can look for Masters in Management programme too, which doesn't require much experience.
