Hello Jeevan

If you are expecting a marks of around 47.67 i.e below 50 then brother chances are bleak. As you know this time IIt Madras conducted the paper and it turned out to be easy as compared to last 3-4 year.

So, in this marks you can into NIt's but speacialization i can't say as it will be tough. IIt's will be tough this time (top 7). But considering OBC then you can get NIT's like Rourkela or Shuratkal (may be).
