UPSC IFS (Forest) syllabus

Prelims

  • Same two papers and syllabus as the Civil Services prelims
  • Separate cut-off for the forest service list

Mains: compulsory papers

  • General English: an essay, plus questions on understanding English, summary and precis
  • General Knowledge: current events, everyday science, Indian polity and Constitution, history of India and geography

Mains: optional subjects (choose any two)

  • Agriculture, agricultural engineering, animal husbandry and veterinary science, forestry
  • Botany, zoology, chemistry, chemical engineering
  • Civil engineering, mechanical engineering, geology
  • Mathematics, physics, statistics

What they ask

The first hurdle is the Civil Services prelims, but the forest service has its own cut-off and the mains list is about twelve to thirteen times the vacancies. The mains asks for two optional subjects, two papers each, set at honours level (bachelor's level for the engineering subjects). Some pairs are barred, such as mathematics with statistics, agriculture with forestry, or more than one engineering subject. All mains papers are in English, and the interview carries 300 marks with no minimum.

How to prepare

  • Check your optional pair against the barred list in the notice before you start. Mathematics with statistics or agriculture with forestry, for example, is not allowed.
  • Prepare for the Civil Services prelims as your base, since the forest service shortlist comes from the same GS Paper I and CSAT papers.
  • Pick optionals close to your degree. Each carries 400 marks and is set at honours level, so a subject you studied for three years saves months.
  • Write the mains in English from the start of your practice, because the notice allows no other medium for this exam.
  • Revise general studies with daily topic-wise practice quizzes on the free Improvam app.
