The University of Kerala should roll back the hike in the fee for revaluation and scrutiny of the LLB answer papers, the Progressive Students Union (Marxist) has demanded. A pressnote issued here on Saturday said the fee had been hiked sharply from Rs. 150 per paper to Rs. 500 per paper. Each semester has four to five subjects. A student from a financially backward family would find it hard to pay so much money for getting his answer papers scrutinised or revaluated, the press note said.
