Use of Whitener in OMR
Some youtube channel recommended taking whitener in exam. He said he has used it many times and in multiple exams including UPSC and it was marked correct according to him.
So anyone else here who has used whitener in OMR, does it work ? Can I reply on it in rate chance that I mark wrong in OMR ?
