This app allows you to study using problem sets you create yourself on your smartphone. Whether for qualification exams, school tests, or memorization, you can repeatedly study your original problem sets anytime, anywhere.

■ Recommended for:
・Those who want to use their own flashcards or question-and-answer sets on their smartphone
・Those who want to study with a personalized problem set that isn't available in commercially sold problem sets
・Middle school, high school, university, and working adults who want to efficiently use their free time during commutes
・Those who want to focus on reviewing only the problems they struggle with

■ Main Features
【Import from File】
You can import problem sets from CSV and JSON format files. You can import problem sets created with spreadsheet software or text editors directly into your smartphone and use them for studying.

【Two Question Formats】
・Self-Scoring: A format where you check your answers and determine whether you "got it right/wrong" yourself.
・Multiple Choice: A format where you choose the correct answer from four options.

【Three Learning Modes】
・Random Questions: Questions are presented in a random order.
・Only Incorrect Questions: Review only the questions you got wrong last time.
・Only Unstudied Questions: Start learning from questions you haven't yet solved.

【Genre/Question Set Management】
You can organize multiple question sets by genre. You can classify and manage them according to their purpose, such as qualification exams, school subjects, and business knowledge.

【Resume Learning Midway】
Even if you interrupt your learning midway, you can resume from "where you left off" the next time you open it. Your learning history and proficiency level are also automatically recorded. ## Rankings - #2,946,460 — Overall ## Similar extensions and apps - [TestMaker](https://chrome-stats.com/d/jp.gr.java_conf.foobar.testmaker.service) — 793,690 users, 4.41 / 5 - [脳に定着しやすい問題集（定着問題集）簡単作成！脳にいい学習！](https://chrome-stats.com/d/work.androidkaihatsudomain.AG002_mondaisyuu) — 10 users - [どこでもStudy!自作の問題でスキマ時間に学習しよう!](https://chrome-stats.com/d/com.nbtpApp.study_anywhere) — 643 users - [Copipe - コピペして勉強するアプリ](https://chrome-stats.com/d/com.iffthen.copipe) — 21 users - [Study Question Maker](https://chrome-stats.com/d/com.habibullah.jobcircularhub) — 15 users - [Custom Exam (Help self-learnin](https://chrome-stats.com/d/com.wonderland.memoryhelper) — 1,034 users - [学びの友 旺文社 公式学習アプリ](https://chrome-stats.com/d/jp.co.obunsha.manatomo) — 60,906 users - [中学受験自作問題](https://chrome-stats.com/d/com.modaile.jhsselfmadequestion) — 1,451 users - [学研『スマホ問題集 高校入試 英語・数学・国語・理科・社会』](https://chrome-stats.com/d/jp.co.gakken.smartstudy) — 24,265 users - [FlashCard Study](https://chrome-stats.com/d/com.devfinix.flashcardstudyapp) — 1 users - [Smart Quiz Creator](https://chrome-stats.com/d/com.smartquiz.creator.offline) — 22 users - [Repasapp](https://chrome-stats.com/d/com.heartom.quizmaker) — 5 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.mamorite.qbmaker)
