How do I read the opening and closing ranks?

For each college-branch-category-quota combination, the opening rank is the best (smallest) rank allotted a seat and the closing rank is the last (largest) rank allotted in that round. If your WBJEE rank is numerically smaller than or equal to the closing rank, someone with your rank secured that seat that year. The year-level figure we show is the closing rank of the final round; per-round opening and closing ranks are kept in the round-wise data.
