Key Points at a Glance
- 1
The 2026 CET Senior Secondary India-geography scope is: physical features; major rivers, dams, lakes and oceans; wildlife and sanctuaries; disaster management and climate change.
- 2
India is revised through six broad physical divisions: the Himalayan Mountains, Northern Plains, Peninsular Plateau, Indian Desert, Coastal Plains and Islands.
- 3
Himalayan rivers such as the Indus, Ganga and Brahmaputra have perennial flow, while many Peninsular rivers such as the Narmada, Tapi, Godavari, Krishna, Kaveri and Mahanadi depend strongly on monsoon rainfall and plateau relief.
- 4
Major dam-river pairs for school-level map revision include Bhakra-Nangal-Sutlej, Hirakud-Mahanadi, Sardar Sarovar-Narmada, Tehri-Bhagirathi and Nagarjuna Sagar-Krishna.
- 5
India faces the Arabian Sea, Bay of Bengal and Indian Ocean; these water bodies influence monsoon winds, cyclones, ports, fisheries and coastal hazards.
- 6
Common sanctuary-species or habitat links include Kaziranga-one-horned rhinoceros, Gir-Asiatic lion, Corbett-tiger landscape, Sundarbans-mangrove tiger habitat and Keoladeo-wetland birds.
- 7
Disaster management means prevention, mitigation, preparedness, response, relief, recovery and reconstruction, not only rescue after an event.
- 8
Climate-change preparation should connect heat waves, floods, droughts, cyclones, glacier-related risks, sea-level rise and resilient local planning.

Official Scope and Study Boundary
For CET Senior Secondary 2026, use the current RSSB Senior Secondary advertisement as the syllabus boundary. In India geography, the listed bullets are: physical features; major rivers, dams, lakes and oceans; wildlife and sanctuaries; and disaster management and climate change. The preparation boundary is therefore school-level physical and environmental geography, not the wider graduation-level economic-geography block.
The practical study method is map-first. Mark a landform, then connect it with water, habitat and risk. The Himalaya gives high relief, glaciers, fast rivers, forests and landslide risk. A plain gives alluvial deposits, easier settlement and flood risk. A plateau gives older rocks, waterfalls and east- or west-flowing river routes. A desert gives low rainfall, sparse vegetation and water stress. A coast gives sea influence, ports, fisheries, cyclones and coastal erosion.
For one-mark questions, do not memorise isolated names. Revise pairs: physical division plus feature, river plus basin, dam plus river, water body plus coastal effect, sanctuary plus species or habitat, disaster plus preparedness step.
