Environment Ecology

With the change in format since 2011, UPSC is constantly giving more weightage to ‘Environment Section’. There can be various reasons to it from inclusion of Indian Forest Services (IFoS) to increasing worldwide environmental concern.

The importance of Environment can be seen from the fact that it constitutes around 25-30 percent of the General Studies Paper 3. Skip this at your own risk.

How to Prepare

There are many books and coaching notes in the market but seeing the dynamic and unpredictable nature of the subject, there is no concrete material available. Considering this many aspirants find it difficult to prepare and lose substantially in Prelims. Aspire IAS provides you everything at one place by our PT oriented specialized batch of Environment. It is very important to know the basics from the NCERT texts or any book, but is that sufficient?

Many aspirants start on a higher note but without knowing the need or essence, they get stuck in between and lose energy. This costs them severely and the vicious cycle of preparation goes on.
