Hi,

For a ST Candidate to qualify JEE Advanced you need to score according to 2022 one must score 8.75% of total marks of the Jee advanced exam, that is in each subject you need to score a minimum of 2.50% marks of the total subject score. That is to say you need to score a minimum of 31 marks.

I hope that was helpful.
