General Studies and General Abilities
BRICS Nations — Remember "BRICS" for Brazil, Russia, India, China, South Africa. Original four (2009) + South Africa (2010). New members (2024): Iran, Egypt, Ethiopia, UAE—mnemonic "I EEU" (I eat you).
Five-Year Plan Eras — 1st Plan (1951): Agriculture base. 2nd-3rd: Heavy industry (Mahalanobis model). Remember "AG-IN-AG-IN" for alternating agricultural vs industrial focus shifts through Plans 1-8.
Monsoon Onset Dates — Southwest monsoon hits Kerala by June 1 (±7 days). Northeast monsoon: October-December for Tamil Nadu. Remember "J-J-A-S" (June-July-August-September) for SW monsoon months covering 80% annual rainfall.
Carbon Cycle Gases — COâ‚‚, CHâ‚„ (methane), Nâ‚‚O. Remember "C-M-N" (Come Meet Now) for the three major greenhouse gases. COâ‚‚ = 410ppm baseline; Methane 21× more potent than COâ‚‚.
Biodiversity Hotspots (India) — Four hotspots: Western Ghats, Eastern Himalayas, Indo-Burma, Sundaland (Nicobar). Mnemonic: "WEIS" (Wise). Norman Myers identified 34 global hotspots; India has 4.
Disaster Types — Natural disasters: "FLED" (Floods, Landslides, Earthquakes, Droughts). Man-made: "FANCI" (Fire, Accidents, Nuclear, Chemical, Industrial). Helps categorize for Disaster Management Act 2005 framework.
Telangana State Studies
Telangana Rivers — Major rivers: Godavari, Krishna, Bhima, Maner. Mnemonic "Go-K-B-M" (Go Keep Building More). Godavari enters at Mancherial; Krishna at Jogulamba district. Total 33 districts as of 2024.
Telangana Formation Date — June 2, 2014 (2/6/2014). Remember "2-6-2" pattern: 2nd state in 21st century after Chhattisgarh/Jharkhand/Uttarakhand, 6th month, 2014 year. K. Chandrashekar Rao first CM.
Mission Bhagiratha — Launched August 2016 for 100% tap water. Remember "B-Tap-100": Bhagiratha = Tap water = 100% coverage. Largest drinking water project covering all 33 districts, 10,600+ villages.
Telangana Minerals (Coal-Limestone-Cement) — "CLC" triangle: Coal in Singareni (SCCL), Limestone in Adilabad-Khammam, Cement industries follow. Remember "SIN-AD-KHA" for Singareni-Adilabad-Khammam mineral belt.
Mental Ability and Logical Reasoning
Syllogism AEIO Statements — A=All (universal positive), E=No (universal negative), I=Some (particular positive), O=Some...not (particular negative). Remember "AEIO" as vowels in order for categorical propositions in Aristotelian logic.
Blood Relations Gender — Maternal side: "Mama's MANa" (Mama/Mausi/Maternal uncle = mother's brother). Paternal: "Papa's Bua-Chacha" (father's siblings). Nephew/Niece = sibling's son/daughter; remember NE-phew = NE-xt generation.
Direction Clockwise — N-E-S-W moves clockwise 90° each. Remember "NEWS" or "Never Eat Soggy Waffles". For 45°: N-NE-E-SE-S-SW-W-NW. Left turn = anticlockwise; Right turn = clockwise always.
Coding-Decoding Letter Position — A=1, Z=26. For reverse: A=26, Z=1. Quick: M=13 (middle), N=14. For opposite letters: A↔Z, B↔Y, C↔X. Remember pairs sum to 27 always (A+Z=1+26).
Seating Arrangement Tips — Circular: n people = n positions but (n-1)!/2 arrangements due to rotation/reflection. Linear: fix one person first. Remember: "Circle÷2, Line×full" for counting formula differences.
Quantitative Aptitude
Divisibility by 11 — Subtract alternate digit sums: (1st+3rd+5th...) − (2nd+4th+6th...). If result is 0 or divisible by 11, original number is. Example: 121 → (1+1)−2 = 0, divisible.
Simple vs Compound Interest Gap — For 2 years: CI−SI = P(R/100)². For 3 years: CI−SI = P(R/100)²(3+R/100). Remember "R²/100²" for 2-year difference formula to find P or R quickly.
Profit-Loss Successive Discount — Two discounts d₁%, d₂%: Total = d₁+d₂−(d₁×d₂/100). Example: 20% + 10% = 30−2 = 28% off. Remember: "Add then subtract product÷100" (always less than sum).
Percentage-Fraction Quick Conversions — 12.5%=⅛, 16.67%=⅙, 20%=⅕, 25%=¼, 33.33%=⅓, 50%=½, 66.67%=⅔, 75%=¾. Memorize these eight for instant calculations in profit/discount problems without pen.
Triangle Area Without Height — Heron's formula: s=(a+b+c)/2, then Area=√[s(s-a)(s-b)(s-c)]. For right triangle: Area=½×base×height. For equilateral side 'a': Area=(√3/4)a². Remember "√3/4" for equilateral shortcut.
Quadratic Root Formula — For ax²+bx+c=0: x = [−b±√(b²−4ac)]/2a. Discriminant b²−4ac>0 (two roots), =0 (one root), <0 (no real roots). Remember "−b±√D over 2a" sing-song pattern.
English Language and Comprehension
Tense Time Markers — Present: now, daily, always. Past: yesterday, ago, last. Future: tomorrow, next, will, shall. Perfect: already, just, yet, ever, never. Remember "A-J-Y-E-N" for perfect tense indicators.
Active-Passive Voice Swap — Subject↔Object swap; verb changes to "be+V3". "He wrote a letter" → "A letter was written by him". Remember: Active doer first; Passive action first, "by" doer last.
Common Idioms (Body Parts) — "Cost an arm and leg" (expensive), "Keep an eye on" (watch), "Break a leg" (good luck), "Cold feet" (nervous). Remember body parts = figurative meanings, not literal.
