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 5 of the CBSE Class 12 Political Science paper carries 6 marks out of 80, checked against CBSE’s own 2026-27 curriculum document. The whole unit rests on one distinction, and an answer that blurs it loses marks no matter how much else it gets right.
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
- The two concepts of security kept strictly apart — this is where marks are won: in traditional security the thing being protected is the state; in non-traditional security it is people. Every later point in the chapter follows from which one you are talking about
- Deterrence, defence, balance of power and alliance building, defined one by one — including the difference students most often miss, that deterrence works before a war and defence once one has begun
- The internal dimension of traditional security, which answers tend to leave out entirely
- The laws of war, and what they permit and forbid — just cause, discrimination and proportionality, and the limits they place on the use of force
- Disarmament and arms control — BWC, CWC, NPT, SALT and START, with what each treaty actually does and the dates that carry marks: 1968, 1972, 1992
- Human security, narrow and broad, and the 1994 UNDP report that set the idea out
- The five new sources of threat, with the migrant-refugee distinction — terrorism, human rights, global poverty, migration and health epidemics; and migrant, refugee and internally displaced person defined separately, because the paper asks you to tell them apart
- What cooperative security actually means — and why it is not simply another word for alliance
- India’s four-part security strategy, with dates
- A 31-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 unit is left out — all six sub-topics are covered. The Cold War Era and US Hegemony in World Politics are printed in the NCERT book but were removed from the 2026-27 syllabus, so they appear nowhere in this set. The Cold War background needed to make sense of deterrence and the balance of power is given where the argument requires it — but it is background, not an examinable chapter.
