India’s rankings on global indices and more can be helpful for the environment section.
  3. Check previous years’ questions asked in both prelims and mains examination. Not that questions might get repeated, but the candidates get an idea on what sort of questions are targeted and from which topics. This way they can align their preparation as per the need of the hour.
