Environment & Ecology Preparation Strategy

*What to Read

One of the main problems is that there is a question of sources from which to read in the thinking of aspirants. Either you don't know which books you can read or you can read too many books and web articles to believe you covered the whole issue.

One cannot read every topic in subjects like Environment and Ecology, as their contents are wide and the contents are not rigid and the subjects are dynamic so that the contents they read are limited in order to use the quality.

Difficulty in Understanding

The difficulty to understand the notion in the first reading is a key challenge with these topics. Through reading these subjects, aspirants become bored and indifferent. Therefore, patience is the essential factor needed to prepare the subject. When a student reads the same information twice to three times, he finds it easy and intriguing. But at least five times should be reviewed to remind you of the contents examined.

Covering Current Affairs

The environment is a dynamic topic and hence requires a dynamic approach as well. Questions about environmental, ecological and biodiversity events in the last year or so are asked. Aspirants must be well informed of these occurrences. The BPSC Prelims Paper has more frequently asked questions about the international organisations, conventions etc, as they are so asked of current occurrences, thus it is very vital to review and read them.

Best Books for BPSC Environment & Ecology

For the environment and ecology, students should choose a book that contains all the key principles and basic data and besides that, the newspapers etc. must cover all other dynamic parts. Check all the BPSC Books for both Prelims and Mains. 

  • For the static part, refer to the NCERT textbooks of Geography (classes VI to XII), biology (classes XI and XII) (Download NCERT Books
  • India Year Book: Environment and Geography Chapters
  • The Hindu and Down to Earth newspaper
  • Science Reporter magazine

One of the basic books should be selected by the students. You should read it at least three times, even if you are bothered to read it.
