AP Police PC tricks & mnemonics — save minutes on exam day
Subject-wise short tricks and memory hacks for AP Police Constable (APSLPRB). Each one is meant to be used in the exam hall — read it, then lock it in with a quick practice question.
Direction: NEVER Eat Soggy Waffles — Clockwise from top: North, East, South, West. Right-turn = clockwise (N→E→S→W), Left-turn = anticlockwise. 90° right twice = 180° about-turn.
Coding: Position Values A=1, Z=26 — For letter-number coding: A=1, B=2...Z=26. Reverse: A=26, Z=1. Remember EJOTY positions: E=5, J=10, O=15, T=20, Y=25 (multiples of 5) as anchors.
Syllogism: "No + Some = Some Not" — Combine conclusions: No A is B + Some B are C = Some C are not A. Also: All + All = All (chain works); All + Some = No conclusion (weakest link rule).
Dice Opposite Faces: Sum = 7 — On standard dice, opposite faces always sum to 7: (1,6), (2,5), (3,4). Use this to eliminate impossible cube-net foldings instantly.
Seating Arrangement: Clockwise = Opposite — Person to your "right" in circular clockwise seating is "left" from center-view. Draw arrow-direction first; label clockwise or anticlockwise consistently to avoid mirror errors.
Arithmetic (SSC Standard)
Divisibility by 11: Odd-Even Digit Difference — Subtract sum of odd-position digits from even-position digits. If result is 0 or divisible by 11, number is divisible by 11. Example: 1331→(1+3)-(3+1)=0✓
Percentage-Fraction Anchors — Memorize: 12.5%=1/8, 16.67%=1/6, 20%=1/5, 25%=1/4, 33.33%=1/3, 50%=1/2, 66.67%=2/3. Saves calculation time in profit-loss, SI-CI questions.
Profit & Loss: Successive Discounts — Two discounts a% and b%: Net = [a+b-(ab/100)]%. For 20% + 10%: 20+10-200/100 = 28% discount, NOT 30%. Single-formula trick.
Time-Speed-Distance: 5/18 Rule — Convert km/h to m/s: multiply by 5/18. Convert m/s to km/h: multiply by 18/5. Example: 72 km/h = 72×5/18 = 20 m/s.
Simple vs Compound Interest: Year 2 Difference — SI for 2 years = 2P×R/100; CI-SI difference in year 2 = P(R/100)². If difference known, find Principal or Rate instantly.
Time and Work: LCM of Days — Take LCM of individual days as total work units. Then efficiency = Total/Days. For combined work: add efficiencies. Eliminates fraction errors in complex problems.

General Science
VIBGYOR: Light Wavelengths — Violet, Indigo, Blue, Green, Yellow, Orange, Red. Increasing wavelength, decreasing frequency. Red bends least (longest λ), Violet bends most (shortest λ) in prism.
Vitamins: Fat-Soluble = ADEK — Vitamins A, D, E, K dissolve in fat (stored in body). B-complex and C are water-soluble (excess excreted). Deficiency: A=night blindness, C=scurvy, D=rickets.
Indian National Congress Sessions: 1885-1905-1929 — 1885 = Founded (Bombay, Hume); 1905 = Partition of Bengal; 1929 = Lahore Session, Purna Swaraj (complete independence) declared by Nehru. Key 20-year gaps.
Gandhian Movements: "CSQ" — Champaran (1917, indigo), Salt Satyagraha/Dandi March (1930, salt tax), Quit India (1942, British exit). Chronological order with decade gaps (1917-30-42).
Indian Rivers: East vs West Coast — East-flowing (Bay of Bengal): Ganga, Brahmaputra, Mahanadi, Godavari, Krishna, Kaveri. West-flowing (Arabian Sea): Narmada, Tapi. Majority flow east; only two major west.
Fundamental Rights: CREEPS-6 — Six rights: Equality, Freedom, Exploitation (against), Religion, Culture-Education, Constitutional Remedies. Article 32 = Right to Constitutional Remedies (Dr. Ambedkar called it "heart and soul").
Directive Principles: Part IV (Articles 36-51) — Non-justiciable (not enforceable by court). Gandhian: Article 40 (Panchayats), 43 (living wage), 48 (cow protection). Socialist: 39 (equal pay), 41 (work/education).
Current Events and Andhra Pradesh Specific
AP Rivers: GKPV Formula — Godavari (largest), Krishna, Pennar, Vamsadhara. Godavari enters at Bhadrachalam, exits at Rajahmundry; Krishna at Vijayawada. Remember Prakasam Barrage (Krishna), Polavaram Project (Godavari).
AP Districts: 26 Total (2022) — Post-2022 reorganization: Alluri Sitarama R
