Himanshu,

As per previous years records, you need to score atleast 160+ score to get 99+ percentile with your OBC category. With these marks you will be able to secure a rank of below 6,500. And if you are able to secure more than 200 marks then you might secure a good rank below 2000.

Well, you must kindly note that this is just a prediction and it may vary as cutoffs, difficulty level of exam etc , many factors affect the marks vs rank system and it changes every year. you can also use the college predictor link given below:
