Hell Aspirant,

The Indian Institutes of Technology (IITs) practices affirmative action and offers reservation to the "backward sections" of the society. SC/ST/OBC candidates are offered lower admission cutoffs for selection in IIT via reservations. However, all candidates, including SC/ST/OBC candidates, must meet stringent standards. For candidates in the general category, successful students must generally score within the top 0.25% or top 0.5% of all students to gain admission to the IITs, whereas SC/ST/OBC candidates must generally score within the top 2% of all students to gain admission to the IITs.
