Prologue

  • Myself Sunep Jamir, I’m a B.E. Electronics Engineer. For two years I’ve worked in TCS, Delhi and times I’ve written Mains with Geography Optional subject.
  • In this Revision Lecture series, I’ve be covering the important topics of Geography for Mains General Studies paper-1. There won’t be an ‘organic’ flow in the lecture because I’m only covering selected aspects and unique phenomenon, and moving from one topic to another in a speedy manner.
  • Due to technical limitations, the whiteboard is not captured. But since I’m describing as a draw, it should not bear much problem, so please bear with it.
