  • The course includes Geology Optional Book Summaries. All the Standard Book Summaries are uploaded one by one.
  • No book needed: For making content, we start with NCERTs, and refer standard text books, reference books, research papers and journals. We update the optional content with current affairs.

You can solve 54/56 questions in Paper 1 and Paper 2 in UPSC CSE 2021 Mains from Previous Year Papers. View Source of Questions

You can solve 52/56 questions in Paper 1 and Paper 2 in UPSC IFS 2021 Mains from Previous Year Papers. View Source of Questions

All these questions can be solved if you have followed Synopsis IAS, because Synopsis IAS make content from Previous Year Papers + Syllabus. View More

  • Strategy Videos by Krishna Sir: Previous Year Questions for Geology Optional UPSC is discussed in detailed manner, in which the strategy for Answer Writing in Geology Optional is covered.
    • You will be able to self-evaluate the answers after going through these videos.
    • You will learn to apply paper 1 concepts in Paper 2; use tables, charts, examples etc.; and implement other important aspects of Geology in your answers.
  • Discussion Videos for Previous Year Questions for Geology Optional.
  • Theory Classes for all the topics in Syllabus.
Our Methodology for content Development
  • We are a content-based coaching. We spend 6-8 hours for a 20-30 minute lecture to provide you the most comprehensive and Synoptic content for UPSC IAS (Indian Administrative Services) and IFS (Indian Forest Services).
  • Our Approach- Syllabus and previous year papers are the Key! It is a well-established fact that at least 90% of questions are repeated directly or indirectly in UPSC Optional Papers. Considering this fact, the content is made while considering two parameters: UPSC Syllabus Plus Previous Year Question Papers.

A Scientific and Redefined Way to Learn Optionals: All the questions from 1979 to 2021 IFS are updated, along with standard book summaries.

Other Features of the courses

  • Advanced lectures: These include applied part and in depth-learning for all major topics.
  • Study Material: Lecture content is available for registered students in PDF E-Book format.
  • Personalized student dashboard: Registered Students get a Personalized student dashboard with a login password. You can watch the lectures anywhere, anytime.
  • Answer Writing Practice: There are extensive answer writing sessions exactly based on UPSC pattern. Kindly note that evaluation is not part of the Classroom course. Evaluation is available for test series students.
  • Model Answers: You will get model answers to the previous year questions, expected questions etc.
  • Expert Support: You will get Doubt clearance Sessions via mail, chat, or phone, as and when required.
  • Offline centre Support at Delhi.
  • Two-way feedback: We take students’ feedback seriously. We can remove or replace faculties if the feedback is not good.
