Hello Aspirant,

The ranks presented under the SC, ST, OBC columns in last year's rank details are category-wise ranks, and not general ranks. The SC, ST, OBC ranks indicate the last rank in the relevant category (SC, ST, OBC) that was assigned in a round/course. For the general/open category the ranks shown reflect unreserved candidates.

For example, SC column shows "2567" and it means that the last admitted SC Category candidate was assigned a category rank of 2567.  The corresponding general rank may not be the same but it is not used for seat allotment in reserved categories.
