What is the Unofficial Math Kentei Pre-1 Quiz?

This is an unofficial free web quiz app for practicing advanced mathematics in a 4-choice format.

All questions, answer choices, explanations, diagrams, graphs, and numerical settings are original. The app does not reproduce official exam questions, official sample questions, official model answers, textbooks, workbooks, entrance exams, mock exams, or other existing learning materials.

Original course structure

The courses are arranged as an independent study path for advanced high-school-level mathematics and related review.

• Pre-1 basics review

Dynamic hints with original diagrams

Hints change according to the current question. The app shows original SVG diagrams for topics such as the unit circle, limits, derivatives, integrals, vectors, complex numbers, and probability.

My Page keeps your challenge history, best records, and often missed questions for repeated review.

How this quiz helps

Each question is designed to help you identify the form, choose a useful formula, and reduce common calculation mistakes. The 4-choice format makes it easy to practice in short sessions before class, after school, or during quick review time.

The hints change with the current question, so you can review the key idea, formula, calculation steps, and common pitfalls immediately after thinking through the problem.

For calculation practice and reasoning review

Short calculation questions help build speed and accuracy, while mixed courses encourage you to decide which method fits the problem. You can also use the quiz as a warm-up before writing full solutions in a notebook.
