This is going to unnecessarily complicate their selection process. They should ideally have had the exam postponed for everyone. The cost of date change on a booked venue and the cost of booking a smaller venue plus invigilators, new set of test papers etc would even themselves out. Why not do the smart thing SG?
Now the normal candidates will have to wait for the Chennai results to come out before they can proceed with subsequent rounds? How are they going to work around this?
