The Challenge of Mains Answer Writing for UPSC!

Many aspirants practice random questions or irrelevant Mains Test Series on various websites, telegram groups and other platforms, hoping to master the art of answer writing. However, this often leads to haphazard practice of writing 200-word answers in just 8 minutes, which ultimately makes little sense.

Moreover, deciphering the correct approach to answer a mains question is a significant struggle for most students. The speculations and ambiguity surrounding which topics are relevant for mains and which are not only adds to the struggles of the students. Consequently, students end up relying on random answer writings from different coaching institutes. And the trap of a Rat Race for Answer Writing starts.

How is this course different from similar courses by other coachings?

Problems with Mains Test Series and Traditional Way of Answer Writing: 

  • Questions are not up to the level of UPSC: Do watch the lectures on sources of questions here.
  • Answer evalutions are not up to the mark.
  • It adds unnecessary 500 pages to your study material (Per test series).
  • It is costly.
  • Free portals for Daily answer writing are time consuming. You will write 5-8 questions daily, for which 99% times questions and content is useless. You are just killing your time rather than getting anything positive. If you do not believe, do check the level of questions, and match those with real UPSC questions.
  • Answer writing becomes burden for you.

Solution: change the approach

  • Mains Answer Writing Mains Answer Building
  • There is no daily answer writing, it removes your burden.
  • The practice questions are taken from UPSC PYQs (always up to the mark).
  • UPSC repeats itself (follow synopsis guidance series for this), so this course helps you to understand UPSC trend.

Other coachings provide too much content.

Still, a number of topics are left out. Students are forced to follow two or three coachings, along with a newspaper like The Hindu, Indian Express, Dainik Jagran etc.

Ultimately, students tend to confuse and get stressed. A number of students even do not appear in the exam due to the phobia of Current Affairs, PT type compilations, The Hindu, Indian Express.

At Synopsis IAS, we provide to the point and Synoptic Content.

No other Study Material / Book needed: For making content, we start with NCERTs, and refer newspapers, standard text books, reference books, research papers and journals. We update the content with current affairs regularly. After making content for any topic, we also refer to the other major institutes notes to ensure that we don't miss any important point or topic.

Still, the content is available in approx 1/3rd pages as compared to the other institutes.

Krishna sir is the content head at Synopsis IAS. The course content is thoroughly reviewed by him. He has gained 7+ years of experience in Research and Development while in services at DAE, GOI.


We do not waste unnecessary time in selling coupons for courses, marketing, and promotions. The faculties just teach, teach and teach, and do not beat around the bush. The lecture duration is short – If other institute has covered the same topic in 1 hour, we cover that just in approx. 15-20 minutes.


We teach in easy Hinglish language. The content slides for the course are in Hinglish (One line English, One line Hindi).

The course is available in English and Hindi Mediums. The Study Material is in Three Languages: First file is in English, Second file is in Hindi, Third file is Bilingual (one line English, one line Hindi). The Lectures are delivered in Hinglish.


When it comes to guidance, noone can even come closer to Synopsis IAS. The Synopsis IAS institute is based on the vision of a person, who left services just to teach and provide genuine Guidance.
