I am from a NON-CS background, Also I had backlogs in 13 subjects.I have completed without any gap year with 6.7 CGPA can I get admission in MS in CS.I have been working with TCS from past 2.7 years?

Since you have the relevant work experience which is perfect for a non IT background person who wants to pursue MS in CS abroad. Though the only problem are your backlogs. You have 13 backlogs which is a big number and as per international standards only 5 backlogs are allowed and having more than 5 backlogs means rejection. If you have any further questions just ask me.
