About this Course

In this course, we are going to cover all the topics of Mathematics Optional for UPSC Mains, with an objective of scoring 360+ marks in the Optional Exam.

The Optional subject has 2 papers: Paper I and Paper II. Each of these papers is of 250 marks, thus making the total optional marks to 500. This is approximately 25% of the total marks (2025) of UPSC Exam (including Mains + Interview). Thus, it becomes extremely crucial to prepare a systematic strategy supported by a balanced and dedicated schedule to score good marks in Optional Exam.

Exam Structure

Maths Optional consists of two Paper: Paper I and Paper II. Both of these papers are paper-and-pen, subjective exams with 3 hours in duration. Each Paper is divided into 2 Sections: Section A and Section B, with each Section having 4 questions. Thus, each Paper has 8 questions with a total of 250 Marks.

Why Maths as Optional

Maths has many advantages over other subjects which can be taken as optional subjects for the Mains exam. Some of these are listed below:

  • Static Syllabus: Syllabus does not change from year to year
  • Objective Scoring: This eliminates the instructor bias in grading to a large extent
  • Less Preparation Time: The logical nature of the exam reduces the preparation time
