New Delhi: Those unhappy with the marred Common Admission Test (CAT) are venting their ire on social networking sites Facebook and Orkut. The IIMs and the American firm Prometric, which is conducting the online test, have come in for intense criticism. "Legal cases can be filed against IIM for harassing students in such a way. Many students came to give exams from remote areas. The institute had enough time to prepare itself for such an emergency. This is playing with the life of several students," said one student on Facebook.
