Hi,

Your overall percentile will be some of marks obtained in physics, chemistry and maths.

So if you get total 130 marks out of 300 in jee main 2020 you can expect an overll Percentile around 97 - 98 . Your Predicted Rank could be around 16000 - 19000

The percentile which you will get depend on many factors like category, number of student appeared, marks obtained by you in comparison to their marks etc.

So the percentile for.marks obtained changes every year. However you can make an idea about the percentile which you can expect from previous years data analysis.
