(Last-day, one-page summary)
1. India – Physical Facts (Must-Cram)
| Fact | Figure | Memory Hook |
|---|---|---|
| Latitudinal extent | 8°4’ N – 37°6’ N | “8-to-37, India’s heaven” |
| Longitudinal extent | 68°7’ E – 97°25’ E | “68-to-97, phone codes we remember” |
| Total land frontiers | 15,200 km | “15-20 party” |
| Coastline (mainland) | 6,100 km | “61-dial coast” |
| Highest peak | Kanchenjunga (8,586 m) | “8-5-86, Sikkim’s fix” |
| Longest river | Ganga (2,525 km) | “G-25, silver train” |
| Largest lake (fresh water) | Wular Lake (J & K) | “Wular → Water” |
| Southern-most point | Indira Point (Great Nicobar) | “Indira in Nicobar” |
2. States & Their Borders (Trick = “Bengal-7, MP-5”)
| State | Number of States sharing border | Bordering states (first-letter) |
|---|---|---|
| West Bengal | 7 | “BOSS NSA” – Bihar, Odisha, Sikkim, Nagaland, Assam |
| Uttar Pradesh | 8 | “UK, HP, HR, RJ, MP, CG, BR, JH” (alphabet order) |
| Assam | 7 | “AN-BN-MN-NA-AR-TR-MI” (NE states) |
| Madhya Pradesh | 5 | “UP-RJ-GJ-MH-CG” (clockwise) |
Shortcut:
UP-8, Bengal-7, Assam-7, MP-5 → 8-7-7-5 (year ‘75 emergency – easy to recall).
3. Soils of India – 60-Second Table
| Soil | Colour | Rich in | Crop | State |
|---|---|---|---|---|
| Alluvial | Light | Potash & Lime | Rice, Wheat, Sugarcane | Punjab, UP, Bihar |
| Black (Regur) | Black | Iron, Lime, Mg | Cotton, Sugarcane | M.P, Maharashtra |
| Red | Red | Potash poor | Millet, Tobacco | TN, AP, Karnataka |
| Laterite | Reddish | Iron & Alumina | Tea, Coffee | Kerala, Karnataka |
| Desert | Arid | Saline | Bajra, Barley | Rajasthan |
Mnemonic for order of soil fertility:
“A-Ba-Re-La-De” → Alluvial > Black > Red > Laterite > Desert.
4. Climate & Monsoon – 4 Magic Numbers
| Event | Normal Date | Exam Favourite |
|---|---|---|
| Onset in Kerala | 1 June | “1-6, school reopen” |
| Delhi onset | 29 June | “29-6, Delhi fix” |
| Retreat from NW India | 15 Sept | “15-9, rain fly” |
| Tamil Nadu gets rain | Oct–Dec (NE monsoon) | “TN-10-12” |
Rainfall Formula (approx.):
Western Ghats > 200 cm;
Ganga plain 100-200 cm;
NW India < 60 cm (desert).

8. Final 10-Point Checklist
- 82°30’ E = IST = Mirzapur
- 23½° N = Tropic of Cancer (8 states)
- 37° N = Northern-most; 8° N = Southern-most
- 1,319 km = India-Pak border length
- 1,640 km = India-China border length
- 1,576 km = India-Bangladesh border (longest)
- 331 km = India-Myanmar border
- 1752 km = India-Nepal border
- 699 km = India-Bhutan border
- 106 km = India-Afghanistan border
Mnemonic for border lengths (descending):
“Bang-Bhutan-China-Nepal-Pak-Myanmar-Afghan” → 1576-699-1340-1752-1319-1643-106 (approx.)
