General Awareness
OSI Layer Mnemonic — "All People Seem To Need Data Processing": Application, Presentation, Session, Transport, Network, Data Link, Physical layers (top to bottom).
Internet Protocol Versions — Remember IPv4 uses 32 bits (4 octets × 8), IPv6 uses 128 bits; IPv4 exhaustion led to IPv6 adoption around 2012.
MS Office Shortcuts Cluster — Ctrl+Z (Undo), Ctrl+Y (Redo), Ctrl+C/V/X (Copy/Paste/Cut), Ctrl+S (Save), Ctrl+P (Print)—practice as muscle memory for speed.
Computer Generation Memory — "Very Large Integrated Circuits": 1st-Vacuum tubes, 2nd-Transistors, 3rd-ICs, 4th-Microprocessors, 5th-AI/ML (1940s-present).
Andaman Capital Triple-A — Port Blair is capital; remember "3 As": Andaman, Archipelago, Administrative hub—located on South Andaman Island.
Union Territories Count — Post-2019 reorganization: 8 UTs including J&K, Ladakh, Delhi, Puducherry, A&N, Chandigarh, D&NH, Lakshadweep—remember "JALDI PCL".
Economic Survey Release — Always presented one day before Union Budget (late January/early February); authored by Chief Economic Adviser, not Finance Minister.
Five-Year Plan Abolished — 12th Plan ended 2017; replaced by NITI Aayog's 3-year action agenda and 7/15-year strategy documents—no 13th Plan exists.
General Intelligence and Reasoning
Blood Relation Gender Traps — Assume gender-neutral unless specified: "Sibling/Parent/Child" can be male/female; don't assume doctor=male or nurse=female.
Clock Angle Formula — |11M - 60H|/2 degrees, where M=minutes, H=hours; quick check: at 3:15, angle = |165-180|/2 = 7.5°.
Odd-One-Out Classification — Check 5 properties in order: Type, Function, Size, Relation, Pattern—whichever differs first is the answer.
Coding Shift Pattern — If A→C (+2), check consistent shift; if mixed, look for reverse alphabet (A=Z, B=Y) or position-value swaps.
Direction Sense Square Rule — Visualize as clock: Right=+90°, Left=-90°, About-turn=180°; facing North+Right=East, track cumulative turns.
Mirror Image Symmetry — Vertical mirror flips left↔right only (b↔d); water image flips top↔bottom (p↔q); asymmetric letters change (R≠Я).
Dice Opposite Faces — Sum of opposite faces on standard die = 7 (1-6, 2-5, 3-4); if two views shown, track which numbers can't be adjacent.
Calendar Day Advancement — Odd days: 365 days=1 odd day, leap=2; century: 400-divisible=0 odd days, else=5; January 1, 2000 was Saturday (anchor date).
Series Missing Term — Check differences, ratios, squares, cubes, primes sequentially; for alphabet: check position values, skip patterns, or vowel/consonant grouping.
