About this app

For aptitude tests for major corporations, reviewing necessary material in a timely manner is more important than solving a large number of problems.

Prepare for all 7 subjects—Numerical Logic, Reasoning, Verbal Comprehension, Data Interpretation, Creative Math, Verbal Reasoning, and Sequence Reasoning—all in one app. It includes self-produced questions and detailed explanations for each subject, and FSRS calculates the next review time based on your memory status for each question.

[Key Features]

Full-range learning by subject

Learn the 7 subjects—Numerical Logic, Reasoning, Verbal Comprehension, Data Interpretation, Creative Math, Verbal Reasoning, and Sequence Reasoning—divided by subject and unit. Progress and accuracy rates are displayed for each unit, allowing you to identify and focus on areas you haven't touched yet or your weak points.

Self-produced questions and detailed explanations

We have included study questions across all units tailored to the test scope and the 5-option multiple-choice format. To ensure you don't just check the answer and move on, we have explained why that answer is correct and why the other options are incorrect. Mock Test

Practice with a realistic exam format where you solve 50 questions within 60 minutes. After completing the test, you can review your scores by subject and the questions you got wrong all at once.

Question Search

Find questions instantly using keywords you are curious about. You can select a search range from passages, answer choices, or explanations to view only questions containing specific concepts.

Selective Study Mode

You can select a range of questions by subject or unit. Turning on "Start Unsolved Questions" allows you to continue solving problems you haven't touched yet.

Continue Solving

Your progress is saved even if you exit the app while solving problems. When you return, you can resume your study from where you left off.

FSRS Smart Review

The review interval for questions you remember well is extended, while frequently missed questions are shown again sooner. You can study at the point when your memory starts to fade, without having to manually select the questions to review for the day.
