"Test Marks: 60
Overall Position: 93rd
Position in Zone: 19th"

Straight from the horse's mouth.
In case candidates are to be shortlisted for the open merit seats as well then top 550 candidates will be called in the open quota.
400 candidates for 7+1 seats in Zonal quota.
Looking at my position I guess every candidate scoring 40+ will be shortlisted.
Good luck guys!
