Deductive Reasoning
- Deductive Reasoning I — Draw valid conclusions from a set of given premises. 12 questions · Difficulty 2 out of 5
- Deductive Reasoning II — Knights & Knaves — On this island, every inhabitant is either a Knight (always tells the truth) or a Knave (always lies) — never both, never neither. Use only what they say to deduce who is who. 12 questions · Difficulty 4 out of 5
- Deductive Reasoning III — Chained Syllogisms — In the style of Lewis Carroll's logic puzzles: invented, nonsense categories (never real-world knowledge) chained through several premises. Your only tool is the logic itself — figure out what necessarily follows, and notice when nothing does. 12 questions · Difficulty 3 out of 5
- Deductive Reasoning IV — Elimination Puzzles — Each puzzle presents a small group of people and a set of clues about their pets, drinks, jobs, cities, or positions — every attribute belongs to exactly one person. Use only logical elimination (never outside knowledge) to deduce the fact being asked. 12 questions · Difficulty 4 out of 5
- Deductive Reasoning V — Hat Puzzles and Common Knowledge — A group of people, each seeing everyone else's hat but not their own. From what they announce — or their silence — you can deduce information nobody told you directly: the mechanism behind the classic hat puzzles and "common knowledge" reasoning popularized by Martin Gardner. 12 questions · Difficulty 5 out of 5
- Deductive Reasoning VI — Recreational Arithmetic Puzzles — A mix of classic clever-arithmetic puzzles: age and speed problems, mixtures, the clock, cryptarithms where every letter is a secret digit, and a classic constrained river-crossing puzzle — the kind of problems popularized by Henry Dudeney and Sam Loyd, where the only tool is basic algebra applied cleverly. 12 questions · Difficulty 4 out of 5
- Deductive Reasoning VII — Chain named inference rules — Modus Ponens, Modus Tollens, Hypothetical Syllogism, and more — across multi-step formal derivations. 12 questions · Difficulty 3 out of 5
- Deductive Reasoning VIII — Correctly negate "all/some/none" statements, translate them into quantifier notation, and tell a valid conclusion apart from the classic trap of confusing contraries with contradictories. 12 questions · Difficulty 4 out of 5
Numerical Sequences
- Numerical Sequences I — Find the pattern governing each sequence and determine the missing term. 12 questions · Difficulty 2 out of 5
- Numerical Sequences II — Letter Sequences — Sequence-completion problems using letters instead of digits, a format common to SHL, Wonderlic, and similar aptitude batteries. Every question uses the same fixed convention: each letter stands for its position in the 26-letter alphabet (A=1, B=2, C=3 ... Z=26) — the same underlying skill as numerical sequences, applied to letters. 12 questions · Difficulty 3 out of 5
- Numerical Sequences III — Numerical Analogies — Numeric analogy problems — A:B::C:? — the same inductive-reasoning skill as numerical/letter sequences, framed as a relationship between a PAIR of numbers instead of a chain. A format common in numerical-reasoning and competitive-exam aptitude sections, closely related to the DAT's Numerical Sequences subtest. 12 questions · Difficulty 3 out of 5
Figural Series
- Figural Series I — Spot the visual pattern in each sequence or group and pick the matching figure. 12 questions · Difficulty 2 out of 5
- Figural Series II — Complete the visual analogy: figure out how the first shape transforms, then apply the same transformation to the second pair. 12 questions · Difficulty 3 out of 5
- Figural Series III — Diagrammatic Reasoning (Operator Chains) — A small set of named operators with a fixed rule (based on the "Diagrammatic Reasoning" format used by real batteries like SHL, Kenexa, Cubiks, Saville, and TalentQ) is applied in order to a figure. This test's 4 operators are: "+1 Side" (increases the side count by one: triangle→square→pentagon→hexagon), "Invert Fill" (toggles between a solid figure and an outline-only one), "Toggle Center Dot" (adds or removes a dot at the center), and "Double the Outline" (adds or removes a second, smaller outline nested inside). The last three are switches: applying the same operator twice in a row cancels its effect and returns that attribute to its original state. Genuinely distinct from -001/-002's implicit rules: here the operators are explicitly named and the chain must be EXECUTED step by step, not inferred as a hidden rule. 12 questions · Difficulty 4 out of 5
Verbal Reasoning
- Verbal Reasoning I — Read each short passage and evaluate the statement (or answer the question) that follows, using only the information given. 12 questions · Difficulty 2 out of 5
- Verbal Reasoning II — Critical Inference — Read each short passage, then judge how well the proposed inference is supported by it — not whether it's plausible in general. Five options every time: True, Probably True, Insufficient Data, Probably False, False. 12 questions · Difficulty 3 out of 5
- Verbal Reasoning III — Analogies — Each question presents a pair of words related in a specific way (synonyms, antonyms, part-to-whole, cause-effect, function, category, degree, sequence) — find the word that completes the second pair with the SAME relationship. The classic format from cognitive-aptitude batteries like Wonderlic and CCAT. 12 questions · Difficulty 2 out of 5
- Verbal Reasoning IV — Argument Evaluation — Identify named logical flaws in real-world arguments, and determine what evidence would strengthen or weaken an argument — the critical skill of EVALUATING reasoning, not just drawing conclusions. 12 questions · Difficulty 4 out of 5
Spatial Reasoning
- Spatial Reasoning I — Mentally rotate, mirror, and fold flat figures to find the matching option. 12 questions · Difficulty 3 out of 5
- Spatial Reasoning II — Predict where holes appear when a folded, punched sheet of paper is unfolded. 12 questions · Difficulty 4 out of 5
- Spatial Reasoning III — Visualize what the cross-section of a 3D solid looks like when it's sliced by a plane — the same kind of spatial visualization used in DAT Space Relations tests. 12 questions · Difficulty 4 out of 5
- Spatial Reasoning IV — Cube Counting (Painted Faces) — Count the unit cubes in an assembled, painted 3D solid -- including cubes hidden from view -- and work out how many have exactly N painted faces, the same reasoning used in the DAT Perceptual Ability Test's Cube Counting subtest. 12 questions · Difficulty 3 out of 5
- Spatial Reasoning V — Block Pattern Construction — Match, spot, and count differences in tiled block patterns: each tile is split into four shaded triangles, and you compare a target grid against candidates -- the same visuospatial matching skill used in block-design tasks across aptitude testing. 12 questions · Difficulty 4 out of 5
Truth Tables & Syllogisms
- Truth Tables & Syllogisms I — Evaluate logical expressions and categorical syllogisms using formal rules — AND, OR, NOT, XOR, conditionals, and quantifiers. 12 questions · Difficulty 2 out of 5
- Truth Tables & Syllogisms II — Simplify and prove logical equivalence by naming and chaining logic laws — De Morgan, Distributive, and more. 12 questions · Difficulty 3 out of 5
- Truth Tables III — Reverse Deduction — Given a formula's final truth value, deduce the truth values of its atomic variables — the inverse problem of building a truth table. 12 questions · Difficulty 4 out of 5
- Truth Tables & Syllogisms IV — Rules of Inference — Derive new conclusions from true premises by naming and chaining the classical Rules of Implication — Modus Ponens, Modus Tollens, Hypothetical and Disjunctive Syllogism, Constructive Dilemma, Simplification, and Addition. A genuinely different skill from II's Rules of Replacement (which substitute equivalent expressions): these rules derive brand-new statements toward a target conclusion, the other foundational half of formal natural deduction taught in every introductory logic course. 12 questions · Difficulty 4 out of 5
Raven-Style Patterns
- Raven-Style Pattern Matrices I — Find the rule governing each row and column of the matrix, then pick the figure that completes it. 12 questions · Difficulty 3 out of 5
- Raven-Style Pattern Matrices II — Figure out how an element's position shifts by row and column, then choose the option that completes the 3×3 matrix. 12 questions · Difficulty 3 out of 5
- Raven-Style III — Figure Overlay (Addition/Subtraction) — Combine two cells' shapes into a third by figure ADDITION (union — nothing is ever removed) or figure SUBTRACTION (shapes shared by both cells cancel out). One of the five canonical rule types identified in Carpenter, Just & Shell's (1990) classic analysis of Raven's Advanced Progressive Matrices — genuinely distinct from -001's single-cell attribute transformations and -002's positional (row/column-index) rules. 12 questions · Difficulty 4 out of 5
- Raven Style IV — Distribution of Three / Distribution of Two — Two more of the five canonical rule types identified in Carpenter, Just & Shell's (1990) foundational task analysis of the real Advanced Progressive Matrices, completing the full taxonomy this category has been building since -001: Distribution of Three (three distinct values of an attribute must appear exactly once in every row and column — a Latin-square constraint) and Distribution of Two (only two values are distributed per row/column, so the solver must first work out which value is missing before completing the pattern — Carpenter, Just & Shell's own analysis found this the single strongest predictor of item difficulty across the whole test). Genuinely distinct from -001's within-cell transformations, -002's positional-index rules, and -003's cross-cell figure combination: this is set-completeness reasoning — working out which value a row or column is missing, not transforming or combining figures. 12 questions · Difficulty 4 out of 5
Estimation Reasoning
- Estimation Reasoning I — Fermi Problems — Break a real-world quantity into a chain of simpler estimates and multiply/divide through — the classic "Fermi estimation" skill used in consulting and product interviews. Pick the closest order of magnitude, not an exact number. 12 questions · Difficulty 3 out of 5
- Estimation Reasoning II — Comparative Fermi estimation — decompose two scenarios and judge which is larger, and by roughly what factor, the classic consulting-interview format. 12 questions · Difficulty 4 out of 5
- Estimation Reasoning III — Physical & Volumetric Estimation (Packing & Capacity) — Fermi-style estimation applied to physical space: given a container's or floor's dimensions (shown as a labeled figure) and a real-world benchmark (item size, packing efficiency, or per-person floor space), estimate how many items or people fit. A genuinely distinct Fermi-problem sub-family from -001's single-quantity chains and -002's two-scenario comparisons — the classic 'how many golf balls fit in a school bus'-style volumetric/packing estimation documented throughout the Fermi-problem pedagogy tradition, which here additionally requires reading dimensions off a figure and applying a packing-efficiency or occupancy-density factor, concepts neither prior test in this category touches. 12 questions · Difficulty 4 out of 5
Data Interpretation
- Data Interpretation I — Numerical Reasoning with Tables — Each question presents a data table (sales, expenses, population, budgets) — read it carefully and compute what's being asked: differences, percentages, averages, and comparisons. Watch for classic traps: the highest single value isn't always the right answer. 12 questions · Difficulty 2 out of 5
- Data Interpretation II — Set Theory and Venn Diagrams — Survey and population word problems solved with the inclusion-exclusion principle — a different representational surface from Data Interpretation I's tables: instead of reading rows and columns, you're reasoning about overlapping groups. A format common in GMAT/GRE-style quantitative sections and case-interview prep. 12 questions · Difficulty 3 out of 5
- Data Interpretation III — Bar Charts — Each question presents a bar chart (branch revenue) — read the axes carefully and calculate what's asked: differences, percentages, averages, and comparisons between two periods. Watch out for the classic trap: the largest absolute increase doesn't always match the largest percentage increase. 12 questions · Difficulty 3 out of 5
Probability Reasoning
- Probability Reasoning I — Probability and Combinatorics — Probability, counting, and expected-value problems like the ones asked in Big Tech technical interviews and quantitative trading firms — from simple coin flips to conditional probability and constrained combinatorics. The only tool needed is careful counting. 12 questions · Difficulty 3 out of 5
- Probability Reasoning II — Bayesian Reasoning and the Base-Rate Fallacy — Conditional-probability problems built around Bayes' theorem and the "base-rate fallacy" — the famous, deeply counter-intuitive result that even a highly accurate test can be mostly wrong when the thing it's testing for is rare. Distinct from Probability Reasoning I: that test covered independent events and combinatorics with a fixed, known sample space; this one is about updating a belief given new evidence, the reasoning skill behind quantitative interviews, medical statistics, and data science. 12 questions · Difficulty 4 out of 5
- Probability Reasoning III — Expected Value and Decision-Making — Expected-value problems applied to decisions under uncertainty — bets, investments, insurance, and decision trees — the reasoning behind quant-trading and finance interviews. Distinct from Probability Reasoning I and II: those calculate a probability or count a sample space; this one uses expected value to decide between options, including when expected value alone isn't the whole answer. 12 questions · Difficulty 4 out of 5
- Probability Reasoning IV — Geometric Probability — Probability where outcomes are spread uniformly over a continuous region — a dart landing on a segment, inside a shape, or within a shaded area — computed as a ratio of favorable to total length or area. Distinct from Probability Reasoning I-III: those count discrete outcomes or evaluate expected value; this one reasons about continuous space using geometry. 12 questions · Difficulty 5 out of 5
Mechanical Reasoning
- Mechanical Reasoning I — Levers, Gears, and Pulleys — Physical/mechanical-principle problems in the style of the DAT Mechanical Reasoning subtest: levers, meshed gears, pulleys, inclined planes, and hydraulics. No formulas to memorize — just how simple machines behave. 12 questions · Difficulty 2 out of 5
- Mechanical Reasoning II — Electrical circuits — series vs. parallel wiring, switches, and how breaking or adding a branch changes which bulbs light up and how bright they are. 12 questions · Difficulty 3 out of 5
- Mechanical Reasoning III — Fluids and Structural Stability — Fluid dynamics/pressure and structural-stability reasoning — pipe flow, buoyancy, communicating vessels, siphons, tipping stability, and tension/compression in simple structures. The "Fluid Mechanics" and "Stability" sections of Bennett/Ramsay/SHL-style mechanical comprehension batteries, distinct from -001's levers/gears/pulleys and -002's electrical circuits. 12 questions · Difficulty 4 out of 5
Quantitative Aptitude
- Quantitative Aptitude I — Profit, Interest, Ratios & Speed — Applied arithmetic word problems in the style used by HackerRank, TestGorilla, and campus-recruitment aptitude tests: profit and loss, simple and compound interest, ratios, percentages, averages, partnerships, and time-speed-distance. Standard formulas, applied carefully — several questions have a tempting wrong answer for anyone who rushes. 12 questions · Difficulty 2 out of 5
- Quantitative Aptitude II — Data Sufficiency — The "Data Sufficiency" format used by the GMAT and other top business-school/quantitative hiring assessments: instead of solving a problem, you judge whether the given information is ENOUGH to solve it. A genuinely different skill from Quantitative Aptitude I — no calculation is the goal, careful reasoning about what's actually needed is. Every question uses the same 5 fixed answer choices. 12 questions · Difficulty 4 out of 5
- Quantitative Aptitude III — Path Optimization — Trace a network of arithmetic operations from node to node, applying each operation in the order of the chosen path, to calculate or compare final results — and find the path that maximizes or minimizes the outcome. 12 questions · Difficulty 4 out of 5
- Quantitative Aptitude IV — Number Properties — Integer and number-theory reasoning — divisibility, prime factorization, GCD/LCM, odd/even parity, remainders, units-digit cycles, and factorial trailing zeros. The single most-tested arithmetic content area on the GMAT Quant section, at roughly 5-7 questions per exam. 12 questions · Difficulty 3 out of 5
Attention to Detail
- Attention to Detail I — Code and Record Comparison — Careful, character-by-character comparison tasks in the style of DAT's Clerical Speed and Accuracy subtest and the "attention to detail" tests used by TestGorilla and Criteria: matching codes, spotting mismatches, and checking records. No trick logic — just careful, systematic comparison, the way real data-entry and quality-control work actually happens. 12 questions · Difficulty 2 out of 5
- Attention to Detail II — Proofreading and error detection in business text — spelling, confusable words, agreement, and numeric cross-checks. 12 questions · Difficulty 2 out of 5
- Attention to Detail III — Visual Comparison — Spot-the-difference and exact-match visual comparison among near-identical simple figures — a perceptual-speed skill distinct from figural-series' abstract pattern-rule reasoning. The "Attention to Detail (Visual)" typology used by hiring platforms like TestGorilla, alongside SHL's related "Visual Comparison" assessment. 12 questions · Difficulty 3 out of 5
Conditional Reasoning
- Conditional Reasoning I — Tell necessary conditions apart from sufficient ones, decode 'only if'/'unless'/'provided that', and spot the classic fallacy of treating one as the other. 12 questions · Difficulty 3 out of 5
- Conditional Reasoning II — Chain conditionals through their contrapositives, tell 'must be true' apart from 'could be true', and find the missing necessary assumption in an argument. 12 questions · Difficulty 3 out of 5
- Conditional Reasoning III — Parallel Reasoning — Given an argument, find — among options from completely different content domains — the one with EXACTLY the same logical structure, regardless of surface-level similarity. 12 questions · Difficulty 4 out of 5
- Conditional Reasoning IV — Necessary & Sufficient Assumptions — Diagnose the assumption an argument secretly depends on. Apply the negation test to find what's necessary, and gap-bridging to find what's sufficient to guarantee the conclusion — the LSAT/GMAT 'assumption family,' confirmed across both exams. 12 questions · Difficulty 4 out of 5
Cognitive Ability
- Cognitive Ability Test — A timed, mixed-format battery — matrix reasoning, number series, verbal analogies, logical deduction, and spatial visualization — like the cognitive-ability sections used by TestGorilla, Criteria's CCAT, and SHL. 25 questions sampled from a larger bank each attempt; no going back once you move on. 25 questions · Difficulty 4 out of 5
