If you have been a serious aspirant and have made notes from Newspapers like the Hindu, you’re in a safe place to revise. If not, you’ll have to go through websites that provide a monthly update on events around the world.

In recent times, environmental issues have been hitting headlines and attracting attention from global leaders and people around the world. A good number of questions are asked every year from environment related topics in the Civil Services Preliminary Exam.

Geography is an important topic for IAS Preliminary as well as Main Exam. The discipline of Geography is broadly divided into Physical Geography and Human Geography.
