Yes, an ST  student with an 80 percentile in JEE Main Paper 2 (B.Arch) has a strong chance of securing admission to the Bachelor of Architecture program at several National Institutes of Technology (NITs), depending on the specific rank and seat availability.

• Exact Rank Matters : While percentile gives a general idea, admissions are based on All India Ranks (AIR) . An 80 percentile typically corresponds to an AIR that may be within the range of previous years' cutoffs for ST candidates.

• Home State Quota : Some NITs reserve a certain percentage of seats for candidates from the home state. If you are applying to an NIT in your home state, your chances may improve.

• Seat Availability : The number of seats in the B.Arch program varies across NITs, which can influence the cutoff ranks.

• Participate in JoSAA Counseling : Ensure you register for the Joint Seat Allocation Authority (JoSAA) counseling process, where seat allotments are made based on AIR and category.

• List Preferences Wisely : Prioritize NITs based on previous years' cutoff trends, location, and personal preferences.

• Consider Other Institutes : Explore options in other reputed institutes offering B.Arch programs where your rank may be competitive.
