New Delhi, Aug 2 (IANS) The supreme Court Tuesday said additional 10 percent weightage being given to students from the Other Backward Classes (OBC) in relation to their general category counterparts was an illusion as the cut-off marks for admission vary from college to college and course to course and places them in an uncertain situation.

The apex court bench of Justice R.V. Raveendran and Justice A.K. Patnaik said the admission criterion should be decided before the admission process commences and not after it has been set rolling.

The court said this during hearing on a petition by some students from the Jawaharlal Nehru University here.
