Using the information provided by you in the query that the JEE rank predictor tools it is found that,your probable rank will be 165,204 - 185,204 and your probable category rank range will be 50656 - 58156 your probable percentile will be 80.3 - 82.3.

Last year the cutoff for OBC category was around 45 marks. So if the trend continues, you may be eligible for jee advance.
