Mathematics is the most beautiful and most powerful creation of the human spirit.**Stefan Banach, Polish mathematician**

A UPSC aspirant is often faced with the dilemma of choosing the right optional. Both the papers contain 500 marks and have a massive impact on your selection in the final list. So one should choose their optional subject very carefully after proper due diligence.

Mathematics is the science that deals with the logic of shape, quantity, and arrangement; has evolved from elemental practices of counting, measuring, and describing the shapes of objects. It deals with logical reasoning, quantitative calculation, idealization, and abstraction of its subject matter.

Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.

Candidates who have an interest in Maths and have studied it in their graduation can opt to take Maths as their optional subject. Only candidates that have some academic background in mathematics should consider choosing Maths as it is a technical subject. Most of the syllabus is static so you don’t have to link it with current affairs. Also, since it is objective in nature, it is extremely scoring.

**Some of the Toppers with Mathematics as their optional subject**

Name of the candidate | Year of passing | Rank secured | Total marks (500) MATHEMATICS |
---|---|---|---|

Kanishk Kataria | CSE- 2018 | 1 | 361 |

Ganesh Kumar Bhaskar | CSE- 2019 | 7 | 310 |

Gss Pravenchand | CSE- 2018 | 64 | 342 |

Arth Jain | CSE- 2020 | 16 | 299 |

Utkarsh Kumar | CSE- 2020 | 55 | 322 |

Optional subject marks play an important role in improving your UPSC-CSE all India ranking. Also, if you have not scored well in GS papers, you can still find your name in UPSC-CSE final list if you score well in optional papers.

Sr. | Course & Features | Fees |
---|---|---|

1. | Online Video Lectures for Both Optional Papers 1 & 2 + Study Material in Soft Copy + Test Series | Rs. 30,000/- |

2. | Online Video Lectures for Both Optional Papers 1 & 2 + Study Material in Soft Copy | Rs. 20,000/- |

– The syllabus for this subject is static. It is not linked to current affairs. So, once you are done with the syllabus you don’t have to constantly update your knowledge, you just need to revise__Static Syllabus__- Maths has a high scoring potential compared with other subjects. If you have prepared well and have written the answers correctly, you will most definitely score high marks.__High Scoring Potential__- Since the questions are not subjective or opinion based but factual, the examiner has to give you full marks if your presentation and content are up to the mark.__Objective Marking__

Usually, the cost of MATHEMATICS optional coaching fee is approx. Rs.50,000/- to Rs.75,000/- whereas online coaching costs very less.

While offline IAS coaching has a fixed schedule, online coaching is flexible. Aspirants can save time from traveling between home, college and other places.

One of the biggest advantages of online MATHEMATICS coaching is that no lecture or topic will be missed as you can watch it anytime anywhere on your laptop or mobile.
