Hi,

According to Jossa the preparatory rank list include candidates who have secured at least 2.5% marks in each of the three subjects AND at least 8.75% aggregate marks in JEE (Advanced) 2020 AND are NOT in any of the other rank lists prepared based on JEE (Advanced) 2020.

The preparatory rank list is prepared for admission to preparatory courses offered by IITs.

Hope it helps.
