01

⭐ Arithmetic Fundamentals

Numbers, averages, percentages, profit-loss, interest β€” the topics that appear on EVERY exam

1.1 πŸ”₯ HIGH Number System

Types of numbers (prime, composite, co-prime), divisibility rules for 2–11 (mental shortcuts), HCF and LCM (prime factorisation + Euclidean algorithm), remainder problems (remainder theorem β€” find remainders without dividing), cyclicity of unit digits (7Β²Β³ β†’ last digit? Pattern: 7,9,3,1), indices and surds (rationalisation). Foundation topic β€” tested directly AND embedded inside other topics.

⚑ Shortcut: Unit digit analysis eliminates 2–3 wrong options instantly. Cyclicity pattern (last digit repeats every 4 powers) solves exponent problems in 10 seconds.
1.2 Average & Decimals

Average formula and applications (sum = average Γ— count). Assumed mean method for large numbers. Average in equal-difference series. Weighted mean for combining groups. Error-based questions ("one number was read wrong"). Recurring and non-recurring decimals β€” conversion to fractions. "5 years ago, average age was..." β†’ current average = old average + 5.

⚑ Shortcut: Deviation method β€” calculate how much each value deviates from an assumed mean. Avoids adding large numbers.
1.3 πŸ”₯ HIGH Percentage

Percentage-fraction conversions (1/8 = 12.5% β€” memorise 12 key conversions). "X% more than" vs "X% of." Successive percentage changes (20% increase then 10% decrease β‰  10% increase). Price-consumption-expenditure relationship. Vote-based questions. Base-change problems ("A is what % of B" vs "B is what % of A"). 3–5 questions per exam β€” highest individual topic weightage.

⚑ Shortcut: Derive any percentage from 10%. 15% = 10% + 5%(half of 10%). 35% = 30%(3Γ—10%) + 5%. One multiplication, not long division.
1.4 πŸ”₯ HIGH Profit & Loss

CP, SP, MP relationships. Profit/loss percentage (always on CP unless stated otherwise). Successive discounts: 20% + 10% β‰  30% (it's 28%). Dishonest trader (uses false weights β†’ effective profit). Marked price vs selling price (discount on MP, profit on CP β€” the trap most students fall into). Buy X get Y free offers as percentage discount.

⚑ Shortcut: "20% profit on CP of 500" β†’ 500 Γ— 1.2 = 600. One multiplication replaces 3 steps. Multiplier method: profit = Γ—1.2, loss = Γ—0.8, discount = Γ—0.9.
1.5 Simple & Compound Interest

SI = PRT/100. CI = P(1+R/100)^T - P. Difference between CI and SI for 2 years = PRΒ²/100Β². Effective rate for different compounding periods. Doubling time: Rule of 72 (72/rate = years to double). Present value. Installments and EMI basics. Banking and fintech companies increasingly test this topic.

⚑ Shortcut: Rule of 72 β€” "β‚Ή1L at 8% doubles in 72/8 = 9 years." No calculation needed. SI formula rearrangement for any missing variable in 10 seconds.
Module weightage: These 5 topics account for 40–50% of quant questions across all placement exams. Percentages and profit-loss appear on EVERY exam. Number system questions test pattern recognition speed. Suggested training: 8–12 hours live + 500 practice problems.
02

⭐ Ratio, Work & Speed β€” Application Topics

Ratio, alligation, time-work, time-speed-distance β€” the application problems that test equation setup

2.1 Ratio & Partnership

Ratio, proportion, continued proportion. Direct and indirect variation. Simple partnership (profit ∝ investment) and compound partnership (profit ∝ investment Γ— time). Fixed vs variable cost problems. The skill tested is equation SETUP β€” the math is always simple once the ratio relationship is identified correctly.

⚑ Shortcut: "Ratio given, total given" β†’ distribute total in ratio parts. If ratio is 3:5 and total is 400 β†’ parts are 150 and 250. One step.
2.2 Alligation & Mixture

Alligation cross method: mix two items at different values β†’ find the ratio for a target value. Repeated dilution formula: after n replacements of k litres from m litres, concentration = original Γ— ((m-k)/m)^n. Mixture problems appear as: milk-water, profit/loss mixing, average price of blended items. The alligation cross gives the answer in one visual step β€” no equations needed.

⚑ Shortcut: Alligation cross β€” draw the cross, write values, take differences β†’ ratio is instant. Replaces 5-step algebraic solution with 1-step visual.
2.3 πŸ”₯ HIGH Time, Speed & Distance

Speed = distance/time. Relative speed: same direction (subtract), opposite direction (add). Average speed for equal distances: 2ab/(a+b) β€” NOT (a+b)/2. Trains: add lengths for passing, time = total distance / relative speed. Boats: upstream = boat - stream, downstream = boat + stream. Circular tracks: meeting time = circumference / relative speed. Linear races: head start problems.

⚑ Shortcut: km/hr to m/s β†’ multiply by 5/18. Average speed for equal distances β†’ always use 2ab/(a+b). Train passing platform β†’ total distance = train length + platform length.
2.4 πŸ”₯ HIGH Time & Work

A completes in 10 days β†’ A's 1-day work = 1/10. Combined work: add rates. Pipes and cisterns: filling rate βˆ’ leaking rate = net rate. Efficiency variations: "A is twice as efficient as B." Alternate days work. Remaining work problems. The LCM method eliminates ALL fractions: take LCM of individual times as total work units β†’ each person's per-day output is a whole number.

⚑ Shortcut: LCM method. "A does in 10 days, B in 15." LCM(10,15)=30 units. A = 3 units/day, B = 2 units/day. Together = 5 units/day. Time = 30/5 = 6 days. No fractions anywhere.
Module weightage: TSD and Time-Work together account for 4–6 questions per exam. These are "story problems" that test whether students can SET UP the equation β€” the math is always simple. LCM method for time-work and 2ab/(a+b) for average speed are the two shortcuts that save the most time across all exams. Suggested training: 6–8 hours live + 400 practice problems.
03

⭐ Algebra, P&C & Probability

The topics that separate 80th percentile from 95th percentile β€” highest difficulty, highest reward

3.1 Algebra

Linear equations in 1–2 variables (word problem β†’ equation setup). Quadratic equations: factorisation, discriminant, sum/product of roots. AP: nth term = a+(n-1)d, sum = n/2(2a+(n-1)d). GP: nth term = ar^(n-1), sum formulas. Inequalities: solving, sign analysis. "What's the pattern?" series problems. Focus: translating English into algebra β€” most students fail at SETUP, not calculation.

⚑ Shortcut: For quadratics, sum of roots = -b/a, product = c/a. Skip the quadratic formula for many problems. For AP, always check if middle term = average of extremes.
3.2 πŸ”₯ HIGH Permutation & Combination

Fundamental counting principle. Permutations (nPr): arrangement where order matters. Combinations (nCr): selection where order doesn't. Circular permutations. With repetition. Restrictions: "select 5 from 12, but 2 must be included." Word formation: "How many 4-letter words from MATHEMATICS?" The hardest topic for most students β€” needs PATTERN RECOGNITION over formula memorisation. 2–3 questions per exam.

⚑ Shortcut: Memorise nCr for small n (C(5,2)=10, C(6,3)=20, C(7,3)=35). Complementary counting: "at least 1" = Total βˆ’ "none." Saves algebra entirely.
3.3 πŸ”₯ HIGH Probability

P(event) = favourable/total. Addition rule (OR: P(AβˆͺB)), multiplication rule (AND: P(A∩B)). Conditional probability P(A|B). Independent vs dependent events. Dice, cards, coins β€” the three classic domains. Expected value. Bayes' theorem for advanced problems. "Two dice rolled β€” probability sum is 7?" appears on 50%+ of exams. 2–3 questions per exam guaranteed.

⚑ Shortcut: P(at least 1) = 1 βˆ’ P(none). For dice: total outcomes = 6^n. For cards: total = 52, hearts = 13, face = 12. Memorise these base numbers β€” don't re-derive.
3.4 Venn Diagram

Two-set: n(AβˆͺB) = n(A) + n(B) βˆ’ n(A∩B). Three-set Venn diagrams. "100 students: 60 play cricket, 40 play football, 20 play both β€” how many play neither?" Max-min problems with sets. "At least" and "at most" phrasing. Quick to solve once the diagram is drawn β€” 1–2 questions per exam, usually easy points.

⚑ Shortcut: Always draw the Venn diagram β€” fill from the INSIDE OUT (intersection first, then exclusive regions, then "neither"). Never try to solve set problems algebraically.
Module weightage: P&C + Probability are the HIGHEST difficulty topics and account for 4–6 questions per exam combined. Students who master these topics jump from 80th to 95th percentile. Most students skip these β€” which means those who DON'T skip gain a massive advantage. Suggested training: 6–8 hours live + 300 practice problems.
04

Geometry, Clocks & Calendars

Spatial reasoning and pattern-based topics β€” fewer questions but quick points for prepared students

4.1 Mensuration & Geometry

Triangles: area (baseΓ—height/2, Heron's formula), properties (Pythagorean theorem, 30-60-90, 45-45-90 special triangles), similarity and congruence. Circles: area, circumference, arc/sector. 3D shapes: cube, cuboid, cylinder, cone, sphere β€” volume and surface area formulas. Coordinate geometry basics: distance, midpoint, slope. Focus on the 10 formulas that cover 90% of geometry problems.

⚑ Shortcut: Memorise Pythagorean triplets (3-4-5, 5-12-13, 8-15-17, 7-24-25). Recognise them instantly β€” skip the Pythagorean calculation entirely.
4.2 Clocks & Calendars

Clocks: angle between hands = |30H βˆ’ 5.5M|. Relative speed of hands: 5.5Β° per minute. Straight line (180Β°), right angle (90Β°), coincident (0Β°) β€” how many times per 12 hours? Faulty clocks: gains/loses X minutes per hour. Calendars: odd days method for finding day of any date. Concept of leap year. 1–2 questions per exam β€” quick marks for prepared students.

⚑ Shortcut: Clock angle formula = |30H βˆ’ 5.5M|. Plug in values β†’ answer in 10 seconds. For calendars: count odd days from reference date β€” no need for day-by-day counting.
Module weightage: 2–4 questions per exam. Geometry is medium difficulty β€” formula-based with standard question patterns. Clocks and calendars are LOW difficulty but frequently tested β€” guaranteed 1–2 easy marks for students who know the formulas. Suggested training: 3–4 hours live + 150 practice problems.
05

Modern Assessment Formats (2025–26)

Guesstimation, flowcharts, gamification, Sudoku β€” the newer patterns in Capgemini and Accenture exams

5.1 Guesstimation & Estimation

"How many petrol pumps in India?" "How many tennis balls fit in this room?" Break into components: number of cars β†’ fuel consumption β†’ daily demand β†’ pumps needed. MECE framework (Mutually Exclusive, Collectively Exhaustive). Key principles: start with known facts, round aggressively, multiply/divide confidently. Increasingly tested at product companies (Fermi estimation) and Capgemini game-based assessments.

⚑ Approach: Break the big question into 3–4 smaller questions you CAN estimate. Multiply. State assumptions. The PROCESS matters more than the exact number.
5.2 Flowchart-Based Questions

Follow a flowchart: given input, trace through decision boxes (if/else), process boxes (add, multiply), and arrive at output. Reverse flowcharts: given output, find input. Common in TCS NQT and Capgemini assessments. Tests: careful reading, conditional logic, and arithmetic accuracy under a visual format. Not hard conceptually β€” but unfamiliar format causes mistakes.

⚑ Approach: Trace SLOWLY and carefully. Write intermediate values at each step. Don't try to do it mentally β€” flowchart questions penalise shortcuts, reward accuracy.
5.3 Gamification & Sudoku

Game-based cognitive assessments: Capgemini uses gamified aptitude tests that measure cognitive traits (processing speed, attention, pattern recognition) through interactive games rather than traditional MCQs. Sudoku-type logic puzzles: constraint satisfaction, elimination, backtracking. Practice builds the pattern recognition speed these assessments measure. The format is new β€” the cognitive skills tested are the same.

⚑ Approach: Practice Sudoku daily (builds constraint-satisfaction thinking). For gamified assessments: speed + accuracy matter equally. Familiarity with the format reduces test-day anxiety.
Module weightage: Capgemini and Accenture increasingly use these formats. TCS NQT includes flowchart questions. Guesstimation appears at product companies. Students who've practised these formats have a massive advantage β€” most competitors haven't prepared for them at all. Suggested training: 2–3 hours live + 100 practice problems.
How This Module Is Delivered

Concept + Shortcut + Practice + Mock Test = Every Session

Live Concept + Shortcut Sessions

Trainers teach the CONCEPT and the SHORTCUT together. "Here's why percentage formula works" β†’ "Here's how to solve any percentage problem in 30 seconds using the 10% method." Theory without speed is useless for timed exams

Timed Topic Practice

After every topic: 20-question timed test on the platform. Speed target: 90 seconds per question. Immediate analytics: accuracy, time per question, comparison with batch. Repeat until speed target is met.

Mock Tests with Analytics

Full-length quant mock tests in company-specific formats. Post-test: accuracy per topic, time distribution, weak area identification. "Your percentage accuracy is 90% but probability is 40%" β†’ targeted sprint on probability.

Platform Practice (24/7)

2000+ problems graded by difficulty (basic β†’ moderate β†’ advanced). AI tutor hints (not answers). Practice between sessions. Platform tracks progress: problems solved, accuracy trends, speed improvement over weeks.

What Students Gain

From "I Can Solve It in 5 Minutes" to "I Solved It in 90 Seconds"

Speed: 60–90 Secs Per Question

Every topic has a shortcut that halves solving time: percentage from 10%, LCM for time-work, alligation cross for mixtures, unit digit elimination, multiplier method for profit-loss. Students who know shortcuts solve in 60–90 secs. Students who don't take 3–5 mins. The exam doesn't give 5 mins.

Pattern Recognition: See the Problem Type Instantly

"This is a successive percentage change problem" β†’ apply the formula, answer in 30 seconds. "This is a Venn diagram problem" β†’ draw the diagram, answer in 60 seconds. Pattern recognition comes from solving 200+ problems per topic type β€” the brain classifies automatically.

Know Your Exact Score: Topic-Level Analytics

After 15+ mocks: "I'm 92% accurate on percentages, 78% on TSD, 45% on probability." Precision on WHERE to focus remaining preparation time. No more "studying everything equally" β€” study what needs improvement, skip what's already strong.
