Ans: No, there is no negative marking system in the PRMO examination. In the PRMO previous year question papers, there were questions of 2, 3, and 5 marks. All OMR sheets will be scanned and checked by machines. You must fill in the bubbles in the OMR sheets carefully since any half-filled bubble in the OMR sheet will not be counted during the correction, hence affecting your scores adversely.
