If / Then — Conditional Logic Quiz
Master the logic of if/then conditionals (P → Q). 45 problems across three levels: Foundation covers the truth table for P→Q (vacuous truth, the one false case), Modus Ponens, Modus Tollens, and why Affirming the Consequent and Denying the Antecedent are invalid. Intermediate adds the contrapositive, converse, inverse, biconditional (P↔Q), the disjunction equivalence (¬P∨Q), and hypothetical syllogism. Advanced covers chained conditionals, negation of conditionals (¬(P→Q) = P∧¬Q), tautologies, complex truth value analysis, and edge cases.
Argument Types — Logic & Fallacy Quiz
Identify whether an argument is deductive, inductive, or abductive — and name the logical fallacy when one is present. 45 problems across three tiers: Foundation covers the most common fallacies (ad hominem, straw man, false dilemma, slippery slope, appeal to authority, bandwagon, hasty generalization, appeal to ignorance) and basic argument types. Intermediate adds subtle informal fallacies (post hoc, tu quoque, anecdotal evidence, appeal to nature, poisoning the well, circular reasoning, relative privation). Advanced covers formal fallacies (affirming the consequent, denying the antecedent, modus tollens), validity vs. soundness, equivocation, and abductive reasoning.
Sentence Errors — Grammar Quiz
Spot the grammatical mistake in a sentence and pick the correct replacement for the highlighted error. 45 problems across three tiers: Middle School (subject-verb agreement, apostrophes, comma splices, there/their/they're, double negatives), High School (dangling modifiers, parallel structure, who/whom, subjunctive mood, lie/lay), and SAT Prep (idioms, concision, that/which, restrictive clauses, advanced agreement patterns).
Trig Ratios — High School Math Quiz
Master sine, cosine, and tangent — the three foundational trigonometric ratios. 45 problems across three tiers: Geometry (SOHCAHTOA definitions, 3-4-5 triangles, special angles 30/45/60), Pre-Calculus (reciprocal functions csc/sec/cot, radian conversion, co-function identities), and Advanced (inverse trig, second-quadrant values, Pythagorean identities, real-world triangle applications).
Geometry: Angles — High School Math Quiz
Find missing angles and apply key theorems — pick the correct answer from four choices. 45 problems across three tiers: Geometry I (complementary, supplementary, vertical, linear pair, triangle sum), Geometry II (parallel line angle pairs, polygon interior sums, inscribed angle theorem), and Advanced (multi-step proofs, circle chord angles, exterior angle formulas, cyclic quadrilaterals).
Systems of Equations — High School Math Quiz
Solve linear systems of two equations by substitution, elimination, and word problems. 45 problems across three tiers: Algebra I (simple substitution and system identification), Algebra II (multi-step elimination, multi-step substitution, and real-world word problems), and Advanced (parametric systems, fractional coefficients, three-variable extensions, and SAT-style applications).
Algebra Challenge — High School Math Quiz
Solve equations, factor polynomials, simplify expressions — pick the correct answer from four choices. 45 problems across three tiers: Algebra I (linear equations, slope, basic factoring), Algebra II (quadratics, systems, logs, sequences), and Advanced (pre-calculus, complex numbers, inverse functions, infinite series).
Complete the Phrase — Collocation Quiz
A phrase with a missing word — pick the one that sounds natural in English. Covers the three biggest collocation challenges: which verb fits (make/do/take/have), which preposition follows the verb (rely on, consist of), and classic fixed phrases (burn the midnight oil, foregone conclusion).
