My son is 180 marks in jee advance . What will be his approxmate rank. He belongs to obc catagery.

Santhosh Nair with 180 marks on JEE Advance your son can expect to get a rank around 1000 under the OBC category. Although rank can vary either side drastically because the rank is totally relative and depends on many parameters like your son's performance, other student's performance, the difficulty of the exam, number of students attended the exam etc.

Still, you can expect your son to get a rank in the range where he will have a good chance of ending into a decent IIT with a decent engineering stream.

Feel free to ask if you have any more queries. All the best!!
