  • Graduation subjects as optional enable to score high: If you are really in love with your graduation subjects and excel in it, then it won’t be a problem. Ask yourself, you did graduation according to your choice or certain set of criteria over ride your choices during graduation. If criteria played an important role, then better to leave degree paper as your optional.
  • Following trend of certain subjects: Candidates will end up in disaster, if you are going to follow some trends. Don’t follow your seniors or peers while choosing optional. Further, some coaching institutes also misguide by showing facts and figures. To exemplify, may be your career gurus will say from last ten years first rank holders are opting economics, so better for you also. My piece of advice is please don’t believe it.
