OnlyTests

Read full description

The OnlyTests app is an essential tool for students preparing for their examinations. It is designed specifically for users of the OnlyTests physical books, integrating seamlessly with the book’s content to provide an interactive and structured approach to mastering key concepts and improving exam readiness. To get started, simply add your book by scanning the QR code found in your OnlyTests book. This will log you in or link the book to your profile. Each chapter in the book, such as “Finance” or “Functions” in Grade 12 Mathematics, includes multiple tests. You can begin a test by scanning the QR code printed at the top of that test in the book. After completing a test, submit your answers directly in the app to receive immediate results and detailed feedback. The app also helps you track your progress with a dedicated statistics page. You can view your average scores per chapter, explore recent test results within specific chapters, and review detailed records of your last five attempts. The statistics page also highlights incorrectly answered questions, allowing you to refer back to the solutions in your OnlyTests book. A new feature that provides full question memos directly in the app after completing a test will be available soon. We have also added two powerful learning tools: – Listen to step-by-step explanations for selected questions, helping you understand each method clearly and at your own pace. – Struggling with a question? Simply snap a picture of it and get guided help from an AI assistant designed to support your learning process. NB: This app is a supplementary tool for exam preparation and supports a variety of syllabuses, including NCS and IBE. It is not a replacement for prescribed textbooks and cannot change examination requirements. The solutions in your OnlyTests book are intended as a guide, and students are encouraged to focus on mastering the underlying methods and concepts. Examiners place greater emphasis on understanding and methodology than on final answers. Prepare smarter and achieve academic excellence with OnlyTests.
