Hi Akshatha,
If you check the admission requirements page for the CS department carefully you will come across the following-
'GRE Test: Admitted students typically earn the following scores on the GREGRE quantitative score of at least 155 for MSGRE verbal score of at least 145 for MSA sum of verbal and quantitative GRE scores of at least 300 for MS. So you require a score of 300 and above to be considered.
I hope this answers your query. Good Luck.

For higher studies, you can go with GRE or CAT also. GRE is basically for students who want to pursue there higher studies abroad, specially in US. CAT is to get into Indian MBA colleges. Getting good marks in these exams can place you in one of the finest universities in India as well as abroad.

A score of 277 on GRE is in no way good. You need to take the GRE again and target a score of 300+ for decent CS programs.

Hi,
10 backlogs is too much so you need to clear that first. Otherwise look for a Diploma and then Masters degree. Other option is to take admission in private universities which might cost you more. Make a decision first and feel free to revert here.
