UPSC vs UPSCTREE

Fujiwhara Effect: The Fujiwhara Effect happens when two spinning storm systems get close to each other. They start to rotate around a shared centre point. It is named after Sakuhei Fujiwhara, the Japanese scientist who first explained it. This was in the news: November 2025. NOT covered in our Tests.

Tundra regions are ecologically fragile due to an extremely slow recovery rate from disturbances, while their immense reserves of oil, gas, and minerals make them economically vital.

This is less about Arid Landforms and more about mechanisms active in an arid environment — covered in test and class. You have to discuss deflation, abrasion, saltation etc. and how they aid desertification and land degradation.

This is an expected question, in line with the weaponisation of water in geopolitics given the status of the Indus Water Treaty. You have to write about the Indus Water Treaty, the Teesta dispute etc. — both covered in RATTAFY.

This question was asked on the backdrop of the Amar Jain Case of 2025. Also you have to do an analysis of Sugamya Bharat Abhiyan as well. Also, while discussing disability: discuss both physical and mental disability.

This question is probably the easiest one on the paper. You have to discuss how digital technology creates both social empowerment and social disempowerment.

For example: AI will increase inequality between people as well as between nations. Same goes for social media and other tools. At the same time, AI and other tools also act as a leveller. You also have to discuss the Digital Divide, and you can bring in Digital Public Infrastructure.

Covered extensively in Tests, Classes and Essays.

Covered in Medieval India, and more specifically in the Culture classes.

Language fights were a constant in the news over the last two years — this is part history, part polity, and this was a highly expected question. Start with Odisha (pre-independence) and then move to the Andhra example (post-independence).

We gave a slightly tougher version of this in our tests — language fights are going on, and this was a highly expected question.

You can answer this if you have read Spectrum Modern India, though note that Spectrum does not cover the Odisha part.

This is Economic History 101 — easy to answer if you’ve read India After Gandhi or Bipin Chandra’s history book. You can also bring in growth centre and growth pole theories while discussing this (how we wanted to push industrialisation by putting industries in backward areas, expecting it to eventually result in forward-backward linkages and overall growth of that region — at places it worked and at places it failed). Also mention how our political leadership was particularly inspired by the Soviet Model. Covered in Modern India Classes and the Foundation course, but not in the test series.

Not covered in Tests, but covered in the Essay Topic: “The 21st Century is Asian” — the Indo-Pacific was a sub-theme of that essay.

This is not asked directly, but discussed across several other questions. You have to write about Population and Urbanization, Agriculture Expansion and Intensification, Infrastructure development, Industry and Mining, and Deforestation etc. and how each contributes to land-use change. Remember, though, that land-use change is a small aspect overall — large parts of India’s land use have stayed the same for more than a century.

Yes and no. Caste as tied to profession has almost disappeared in urban India, except in a few professions. But caste is still relevant even in urban India — especially in matrimony and other social functions. You have to give evidence of both sides.
