Click any module to expand. The golden rule of reasoning: DRAW IT, DON'T THINK IT. Family trees for blood relations, grids for seating, Venn circles for syllogisms. Students who draw solve faster and more accurately than students who reason verbally. Every topic card shows the DIAGRAM METHOD alongside the concept.
Identify patterns, decode rules, classify elements — the speed-based reasoning topics
Letter coding: shift patterns (A→D = +3 shift for each letter), reverse alphabet coding (A↔Z, B↔Y), mirror coding. Number coding: assign numbers to letters with rules. Symbol-based coding: newer TCS NQT format where symbols replace operations. Alphanumeric coding: mixed letter-number substitution. "If COMPUTER = RFUVQNPC, what is PRINTER?" — identify the rule from the example, apply to the new word. 3–5 questions per exam — highest individual reasoning topic weightage.
Find the pattern and predict the next/missing term. Number series: arithmetic (+3, +5, +7...), geometric (×2, ×3...), alternating operations (+2, ×3, +2, ×3...), difference series (differences between terms form their own pattern), square/cube-based (1, 4, 9, 16...). Alphabet series: skip patterns, alternating vowel-consonant, position-based. Wrong number in series: one number doesn't follow the pattern — identify it.
Find the element that doesn't belong to the group. Categories: by type (prime vs composite), by property (all multiples of 3 except one), by pattern (all have same letter structure except one), by meaning (all are fruits except one). Multi-level classification: "All are prime AND less than 20 except one." The trap: there may be TWO possible odd-ones-out — choose the one based on the MOST OBVIOUS classification.
The diagram-based topics — draw it and the answer appears
Linear arrangement: people in a row, fixed positions, relative positions ("A sits 3rd from left, B sits to the right of A but not adjacent"). Circular arrangement: people around a table, clockwise/anticlockwise orientation. Complex arrangements: 2D grid (floor + position), multi-parameter (person + department + city + age). Set-based questions: 5 clues → one arrangement → 3–5 questions from it. These are HIGH-WEIGHTAGE (3–5 questions as a set) and reward systematic diagramming.
"A is the mother of B, B is the brother of C, C is the daughter of D — how is A related to D?" Single-statement questions (quick) and multi-statement set-based questions (5 clues → family tree → 3–5 questions). Gender traps: "brother" = male, "sibling" = either, "parent" = either. Generation mapping: identify which generation each person belongs to. The #1 rule: ALWAYS DRAW THE FAMILY TREE. Never try to solve blood relations mentally — it's the fastest way to get them wrong.
"Start at point A, walk 5km North, turn right, walk 3km, turn left, walk 2km — how far from start and in which direction?" Use a coordinate system: North = up, East = right. Track position as (x,y) coordinates. "Turn right" from North = East, from East = South. Distance from start: Pythagorean theorem on final coordinates. Combined problems: blood relation + direction ("A's father's house is 5km south of A's office"). 1–2 questions per exam — quick marks for students who use coordinates.
Logical deductions, constraint-based puzzles, and visual/spatial reasoning
"All dogs are animals. Some animals are cats." → What definitely follows? Venn diagram approach: "All A are B" = A circle INSIDE B. "Some A are B" = overlapping circles. "No A are B" = separate circles. Draw ALL possible configurations → check each conclusion against ALL configurations → conclusion follows ONLY if true in EVERY configuration. Complementary pairs: "Either conclusion 1 OR conclusion 2 must follow." Logical connectives: AND, OR, IF-THEN, IF AND ONLY IF truth tables for compound statements.
Schedule puzzles: "5 people, 5 days, 5 tasks — assign given constraints." Ranking puzzles: "A scored more than B, C scored less than D, D scored more than A..." → determine order. Distribution problems: "Divide 12 items among 3 people given constraints." Truth-teller/liar puzzles. Grid-based logic puzzles. These test STRUCTURED THINKING under pressure — systematically eliminate possibilities rather than guess.
Symboperation: symbols represent mathematical operations or relationships (♠ means >, ♣ means <). Apply to statements and determine relationship. Ranking: "A is 5th from top, B is 8th from bottom, total = 15" → find A's rank from bottom, B's from top, or if A and B are the same person. Input-output: a machine applies rules to input numbers/words → track through steps → predict output at step N. Each type has a FIXED approach — learn the pattern, don't re-derive each time.
Figure series: identify the pattern in shapes/rotations/transformations → predict next figure. Mirror images and water reflections. Paper folding: fold paper, punch hole → how many holes and where when unfolded? Cube views: given unfolded cube → which 3D arrangement is possible? Dice questions: opposite faces, adjacent faces. Non-verbal patterns: rotation, addition/deletion of elements, shading patterns. These appear on Capgemini game-based assessments and some TCS NQT formats.
Trainers solve problems live using the VISUAL METHOD — family trees, Venn circles, coordinate grids, elimination tables. Students SEE the approach before practising it. "Here's the problem → here's the diagram I draw → here's how the answer appears in the diagram." The process is the lesson.
After every topic: 20-question timed set. Speed targets: 90 seconds per standalone question, 10 minutes per 5-question set. The timer forces students to DRAW instead of overthink — because drawing is faster. Weekly improvement tracked on the platform.
Full-length reasoning mock tests in company formats: TCS NQT (30 Qs/50 min), Infosys, Wipro. Post-test analytics: accuracy per topic type (coding vs seating vs syllogisms), time per question, where students are slowest. "You're 90% on coding-decoding but 50% on seating" → targeted seating practice.
5 minutes daily: one puzzle (Sudoku, grid logic, constraint problem). Builds the analytical thinking MUSCLE that reasoning questions test — the "intuition" that experienced solvers develop. Not exam-pattern practice — THINKING practice. The daily habit that makes all reasoning topics easier over time.
Blood relations → family tree. Seating → grid/circle. Syllogisms → Venn diagrams. Directions → coordinate grid. Coding → EJOTY + alphabet positions. The trained response: "What diagram do I draw?" instead of "How do I think?" Drawing is faster, more accurate than verbal reasoning.
Coding-decoding: 30–45 seconds (identify shift, apply). Blood relations: 60 seconds (draw tree, read relationship). Seating arrangement: 8–10 minutes per set of 5 questions (2 min/question). Syllogisms: 45 seconds (draw Venn, check conclusions). Speed comes from PROCESS, not intelligence.
Seating arrangement sets (3–5 questions sharing one arrangement) are the HIGHEST-VALUE questions on any reasoning section — but most students skip them because they look complex. The grid method makes these SYSTEMATIC: 5 minutes to build the arrangement, then each question answers itself from the grid. Students who master sets outscore those who skip them by 10–15 marks.
After 10+ mock tests: "95% on coding (fast pattern recognition), 80% on syllogisms (Venn method mastered), 55% on seating (needs more constraint-elimination practice)." Per-topic accuracy and speed data. Preparation becomes targeted: practice what's weak, maintain what's strong. Data-driven reasoning improvement.
