QCM is a free Android app developed by AbachraPro in the Education & Reference category. The app is designed to help users prepare for exams by testing their knowledge through a series of questions and answers. QCM stands for "Questions and Answers for Preparation for the Exam," and the app does just that.

Upon opening the app, users are presented with a list of categories to choose from, including mathematics, geography, history, and more. Each category contains a set of multiple-choice questions with four possible answers. Users can select an answer and move on to the next question, with the option to skip a question if they are unsure. Once all questions in a category have been answered, the app displays the user's score and the correct answers to any missed questions.

Overall, QCM is a simple and straightforward app that can be useful for anyone looking to test their knowledge and prepare for exams. The app's user interface is clean and easy to navigate, and the categories cover a wide range of topics. While the app may not be as comprehensive as some other exam preparation apps on the market, it is certainly a good starting point and worth checking out for anyone in need of some extra practice.
