There's 10 % quota for general category. This will help keep some pressure off from general students when preparing for IIT JEE. The admission in public institutions like IIT will likely be through the same process for other backward classes. There are certain benefits that come with the rule-

• Many economically weaker sections in the general category will be helped by the decision.
• It will help boost their morale while preparing for IIT JEE.
• The middle class will highly benefit from the decision. It comes as a milestone decision because earlier there was no reservation for students in the general category.
• Though the competition will still be cut-throat, the students won’t have to take as much pressure as they did in the past.
