Exam-oriented handwritten-style notes — every page laid out like class notes, with highlighting, boxes and a mind map, built to be read the night before rather than skimmed.
Unit 1 of the CBSE Class 12 Political Science paper carries 6 marks out of 80, checked against CBSE’s own 2026-27 curriculum document. It is the chapter that opens the paper and sets up almost everything after it: once the Soviet Union goes, the world has one superpower instead of two, and Units 2 to 7 are all consequences of that single fact.
What is inside
- Chapter at a glance — a one-page mind map of the whole chapter
- Complete topic-by-topic notes, NCERT-aligned, in CBSE’s own topic order
- What bipolarity actually meant, in exam wording — two superpowers of roughly equal strength, NATO against the Warsaw Pact, and most states aligned to one or the other
- The Soviet system’s real strengths, not just its failures — state ownership, a planned economy, a minimum standard of living, and the early lead in space. Answers that only list weaknesses lose marks
- Why the system weakened — stagnation, the one-party grip, alienation, the arms race, and the cost of Afghanistan
- Gorbachev’s reforms and why they ran out of his control — perestroika and glasnost defined and kept distinct, the 1991 coup, and Yeltsin’s rise out of resisting it
- Five causes of disintegration, with the one NCERT calls immediate — the rise of nationalism in the republics, which is the answer the examiner is looking for
- The dates that carry marks — 1917, 1985, 1989, 1991
- Shock therapy set out feature by feature, then cost by cost — privatisation, currency convertibility and free trade on one side; the collapse of the ruble, the dismantled collective farms and “the largest garage sale in history” on the other
- Where the conflicts are — Chechnya, Nagorno-Karabakh and the break-up of Yugoslavia, placed on the map and explained
- India and Russia, and what each side actually gets — the 2001 strategic agreement, oil and gas, defence and cryogenic rocket technology
- A 41-term glossary of every definition the paper can ask for
- 13 board-pattern questions with full model answers
- A revision tracker to tick off each topic as read, practised and revised
Written for the 2026-27 syllabus
Nothing from CBSE’s list for this chapter is left out, and nothing is padded in. Two chapters printed in the NCERT book are not covered anywhere in this set, because CBSE removed them from the 2026-27 syllabus: The Cold War Era and US Hegemony in World Politics. Enough Cold War background is given here for this chapter to stand on its own — but it is background, not a chapter you will be examined on.
