 Previous year Environment and Ecology questions (PYQ) Prelims

Group "A" officers are appointed to various services by the Union Public Service Commission (UPSC), which serves as the primary recruiting organization. 

 

The competitive exam is divided into two phases that go in succession: 

 

  • The Civil Services (Preliminary) Examination, an objective test used to choose candidates for the Main Examination; and
  • The Civil Services (Main) Examination (written and interview) is held to select candidates for the various services and posts.

 

The General Studies Paper-I and General Studies Paper-II (CSAT) are objective-type (MCQ-based) papers that are part of the UPSC Preliminary Examination, the first phase of the exam. To be eligible, you must receive a Paper II score of at least 33%. In Paper I, each correctly answered question is worth two marks, and each incorrectly answered question is worth 0.66 marks, or one-third of a mark. Contrarily, in Paper II, each correct response is worth 2.5 marks, while each incorrect response is worth 0.83 (or 2.5) points less. Both papers must be completed in two hours and turned in on the same day.  

The Preliminary Examination is only intended to be a screening test, and a candidate's final rank or level of service will not be determined by how well they perform on the exam.  

The likelihood of passing this stage is significantly skewed because approximately twelve to thirteen times as many applicants qualify for the main examination as there are openings to fill each year. A candidate must complete the Preliminary Examination to be admitted to the Main examination for that year.  

 

The General category's cut-off scores from previous years are listed below.

To ace the exam, you must study each subject and topic listed on the syllabus. When preparing for Paper-I, it is crucial to finish questions from previous years to comprehend the range of questions asked and predict the questions that might be asked the following year 

There are many questions in the ancient history section of the syllabus. The questions about the environment and ecology listed below were created after carefully examining the UPSC examinations from 2015 through 2022. 

TRENDS AND STRATEGY OF ANCIENT HISTOR 

Most questions about environment and ecology are typically found in the sections on Biodiversity Conservation, Crops and Cropping Pattern, and Biogeochemical Cycles. The crucial topics are Types of Ecosystems, Major Biomes, Pollution & Degradation, and Climate Change. 

Consult the NCERTs for a thorough understanding of the discipline's core concepts. Everyone should also understand the nation's environmental concerns. To supplement the knowledge acquired from NCERTs, current events should be kept up to date, and regular newspaper reading should be done. Readers can also consult publications like the Hindu, the Explained section of the Indian Express, and articles from websites like The Mint and the Hindu Business line to understand contemporary art and culture news.
