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

In UPSC Mains, the course material for Society (GS 1), All subjects of GS 2 (Polity, International Relations, Governance and Social Justice), and All subjects of GS 3 (Economy, Agriculture, Science and Technology, Environment, Disaster Mnagement, Internal Security) is totally different from the Prelims Material.      

This course covers mains specific topics which nobody covers.

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 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.

There are Strategy Videos by Krishna Sir: He has discussed the strategy to prepare for UPSC in cover in a realistic way in his most popular Guidance Series.


The course is available for a very less price compared to any other online or offline coaching.
