Congratulations , you have got some really good marks . The percentile that you have got is based on the number of students that have given the exam in January . The final percentile will only be known after the exam on April . This is so because the percentile is calculated based on the number of students who have appeared the exam.  As of now , the number of students who have appeared the exam is approximately 9.65 lakhs . The net number of students will only be known after the exam of April . 

Hi, first of all, ranks are only being predicted right now. There's no confirmation on it as there will be 2 JEE exams and the normalised rank will only be told after both the exams have taken place. 

From the percentile calculation, your rank will be around 52,500. 

All the best!
