Start with the correct route
Campus BTech: check JEE Advanced and JoSAA rules.
Use JoSAA’s official opening and closing ranks with the correct year, round, institute, programme, seat type and gender pool. JEE Main, JEE Advanced ranks and board marks are different measures. This campus profile is not the separate IIT Madras online Data Science admission route.
Eligibility before score comparisons
Read the current programme bulletin for qualifying subjects, minimum marks, accepted qualifications and any test requirements. A score or previous allocation rank cannot override an eligibility condition. Keep the intended admission session in your enquiry.
Keep each application stage separate
Identify who handles the examination, university application and seat allocation or offer. Where these are separate stages, completing one does not automatically complete another. Use official current notices for dates and keep application and payment acknowledgements.
How to use historical data
Match year, programme, category and round before comparing a score or rank. A historical number is evidence of that allocation, not a forecast. Blank entries should not be interpreted as zero or guaranteed admission. Read the original table’s notes.
