Test Prep Trainer is a free, browser-based practice tool built around the two skill areas that show up on nearly every standardized admissions and placement test: vocabulary and math fundamentals. There's no sign-up, no app to install, and no data leaves your device — everything, including your quiz history and scores, is stored locally in your browser.
The vocabulary trainer covers high-frequency words that regularly appear in reading passages and sentence-completion questions on standardized tests — words like ubiquitous, ambiguous, meticulous, and pragmatic. Study them as flashcards (tap to reveal the definition, then use Prev/Next or Shuffle), or switch to Quiz mode for multiple-choice practice with immediate feedback and a running score.
The math set spans four core categories that make up the bulk of standardized math sections:
Arithmetic — order of operations, fractions and decimals, negative numbers, exponents, square roots, rounding, and LCM/GCF.
Algebra — solving linear equations, systems of equations, evaluating functions, expanding and factoring expressions, and inequalities.
Ratios & Percentages — proportional scaling, percent of a number, percent change, discounts, unit rates, and work-rate problems.
Geometry — area and perimeter of rectangles, squares and triangles, the Pythagorean theorem, circle area and circumference, angle relationships, volume, and slope.
Every question includes a full worked explanation shown immediately after you answer, so you learn the method — not just whether you got it right. Each answer in the bundled question bank was independently recomputed from the underlying numbers during development to confirm it's correct before publishing.
Once you're comfortable with the untimed drills, the Timed Test tab mixes vocabulary and math questions into a countdown-clock practice run — 10 or 20 questions for free, or full 40- and 60-question sets with Pro. When the set ends (by finishing or by the clock running out), you get a score report broken down by category, plus a dedicated review screen listing every question you missed alongside your answer, the correct answer, and its explanation, so you can immediately see and fix the gap.
Your quiz scores, timed-test history, and missed questions are saved automatically in your browser's localStorage — nothing is sent to a server. Pro adds a progress dashboard summarizing your accuracy by category and a missed-question drill that pulls together everything you've gotten wrong across sessions into one focused practice round.
