Hello,

The qualifying cut off percentile to appear for JEE Advanced 2021 is yet to be announced. Last year the cut off percentile for SC category was 50.1760245. It is expected that the cut off percentile this year is going to be in between 50-55. So if you score minimum 50-55 percentile you will have decent chances to qualify in JEE Main. To score such percentile you need to score minimum 35-45 marks in JEE Main. Cut off changes every year depending on total number of candidates appeared, difficulty level of examination and total number of seats available etc. The candidates qualifying in JEE Main are eligible to appear for JEE Advanced.
