Yes, you are. Your score is equal to the accepted score of the top colleges and entrance exams. You can certainly pursue M.Sc from anywhere you want.

First of all, salute to your courage that you cleared your B.Tech till lasts, as there are many more who left it incomplete within 2 or 3 years. You are eligible to MS if you have B.Tech degree but for scholarship it depends on your grades and college of Masters, you are going to join.
All the best.
