How do I use the APPSC Group 2 Mains weightage to plan my study?

What does the 2025 Mains tell me about where my hours go?

The APPSC Group 2 Mains of 23 February 2025 gave each of its four subjects 75 marks. Inside each subject the marks bunched. In science and technology, four chapters on climate, pollution and waste gave 43 marks. Seven technology chapters gave 9 between them. That is about 10.8 marks for each chapter you read against 1.3, roughly eight times as much.

Updated 23 September 2026. What changed

Read each bar as the marks you got back in 2025 for each chapter in that group. Chapters are not all the same length, so treat a chapter as a rough unit of reading time.

The gap is widest in science, and it shows up in each subject. In economy, the external sector gave 12 marks from 2 chapters, while industry, services and IT gave 11 from 8. In AP history, colonial rule gave 13 from 3 chapters and statehood and after gave 6 from 8. In the Constitution, every group gave at least 5 marks, so no part of that book is safe to skip.

The first tab matters for planning months. AP history holds 35 of the 106 chapters, about a third of them, for its 75 marks. Science and technology has 18 for the same 75. Both count the same in your rank. AP history needs more weeks only because there is more of it to read.

Should I study the heavy chapters first?

For the APPSC Group 2 Mains, we would keep the syllabus reading order and let the 2025 marks change two other things: how deeply you learn a chapter, and how often you revise it. Many heavy chapters rest on earlier ones. Balance of Payments gave 12 marks, and it reads far better after National Income, which comes first in the order.

The same holds in science. Climate Change and Climate Action gave 17 marks, the most for any single chapter on the 2025 paper. It sits near the end of the reading order, after Ecology and Ecosystems. Reading it first would mean meeting the words before you have met the ideas behind them.

So a heavy chapter gets more of your past questions, a second and third revision round, and a place early in any last-month revision. A light chapter gets one careful read and a recall check, where you close the notes and write what you remember.

There is one time to go by weight alone. In the last weeks before the Mains, when you cannot revise everything again, revise the heavy groups first.

What can one paper not tell me?

The APPSC Group 2 Mains has run in its two-paper form once, in February 2025. One paper shows where the marks fell that day. It is not a quota the commission has promised to repeat. A chapter that gave nothing in 2025 can carry several questions next time. Read these numbers as a first guide to depth, and read every chapter.

• It is one paper. The next Mains can move marks between groups, and this page cannot tell you how far.
• Zero is not safe. In AP history, 11 of the 35 chapters had no question in 2025. Formation of Andhra Pradesh, 1956 is one of them.
• Some questions touch two chapters, and we counted those in both. Some marks were not placed on any chapter. So a subject totals between 72 and 76 here instead of 75.
• The chapter names are ours. The commission publishes a syllabus, not a chapter list.
• Older Group 2 Mains papers were set to a different format, so they help with chapter practice and say little about this split.

How do I turn this into a week?

Take one APPSC Group 2 Mains subject at a time. Split the week into new reading in syllabus order, recall of what you read, and revision. Let the 2025 marks decide only the revision, heaviest groups first. Below is a worked revision week for science and technology, for someone who has read all 18 chapters once.

Four sittings go to 7 chapters that gave 65 of the 76 marks. Two sittings cover the other 11 chapters, which gave 11. Sitting 6 stays because the next paper can ask these chapters too.

Before you have read a subject once, keep the rhythm in the preparation guide: one new chapter, then recall, then past questions. Add one revision sitting a week and fill it from the top of this order. For economy, AP history and the Constitution, open that subject on the syllabus map and build the same table from its marks column.
