I had joined the following courses at Evolution (GS wing), both in online mode - 1) Interview Preparation Module with  2 in-person mock interview + lectures on Current Affairs and Forestry 2) Prelims modules - Current affairs, Environment and Science-Tech.

It helped me quickly improve my Environmental Ecology preparation from a generalist CSE paper 3 level to the depth required for IFoS. I have seen many of my friends struggle in Environment and SciTech due to lack of a good, consolidated source. Evolution's extremely relevant and comprehensive coverage of these topics definitely added value to my preparation.

Abhishek Sir's lectures were rigorous, yet focused and engaging. The narrative format of delivery improved my understanding, as well as retention, reducing the need for revision. His broader guidance on framing of answers (structuring, prioritisation) was immensely helpful. I would unhesitatingly recommend these courses to any serious aspirant.

Every member of the Evolution team (Abhishek sir, Suman ma’am, Chiranth sir and others) has been a source of immense help, support, guidance and motivation for me.

In fact, now I identify myself also as a part of it. While many persons & institutions helped me in achieving my & my family’s dream, Evolution’s was the most dominant force …the Optimus Prime. I shall always remain indebted to Evolution. Thanks a lot:)

Why do you need coaching for GS? 

GS is the universal requirement

Very good preparation of General Studies is essential to clear any stage of the Civil Service Examination. Without GS, nothing matters in the overall preparation.

The GS syllabus is huge

General Studies syllabus includes topics from more than 10 subject areas, with a large number of open-ended topics. You need guidance and teaching from experts to get a hold on the syllabus.

Good preparation material is not easily available

There is an abundance of free resources but quality study material for GS is still rare. Our concise study material will greatly reduce your workload and time investment.

You may not be equally good in every area

Irrespective of your background, you will need a teacher in many areas of GS. A teacher will simplify the concepts and help you develop a solid command over all topics.

Current Affairs poses a really big challenge

The current affairs section requires simplification, organisation and direction from teachers. Without guidance, this section may be unmanageable.

Understanding the trend is critical

Only an experienced team of experts can help you gain an insight into the pattern of the examination, and give your efforts a proper direction.
