Dafaa: Your Push to Excellence

Notice: Dafaa is not a government app. It is an independent, private app. It does not represent the Algerian Ministry of National Education or any government entity, and it has no link with them. Dafaa (دفعة) is a free app for high-school students in Algeria: physics and chemistry lessons, exercises solved step by step up to baccalaureate (BAC) level, and interactive simulations, all in one place. Your push to excellence. Who is it for? • 1st, 2nd and 3rd year of secondary education. • Streams: experimental sciences, mathematics, technical mathematics, and the common core in science and technology. • For tests, term exams and the baccalaureate. Original content, made by us: Every lesson, explanation, solution and simulation in Dafaa is original content, written by the app's developer (Majal) with a small team of teachers. It follows the Algerian school curriculum taught in public high schools: the same units and the same terms you study in class. The app is in Arabic, like the classes. What you'll find in the app: • Clear physics and chemistry lessons, one part at a time, with a summary for every unit. • Exercises solved step by step, from easiest to hardest, up to BAC level. Try first, then reveal the result and the steps. • Units such as: following a chemical reaction over time, mechanics and Newton's laws, work and kinetic energy, potential energy, conductance… with new units opening through the year. • A lab in your pocket: interactive simulations, even offline. • Lesson questions with their answers. • Unlimited practice: five answers in a day add a day to your streak. • From the magazine to the solution: every exercise in our printed revision magazines has a QR code that opens it in the app. • Practice tests and term exams with their solutions. • A weekly calendar with reminders for tests and sessions. • Live sessions and notifications for every new unit. Subjects: • Available now: physical sciences (physics and chemistry), 1st to 3rd year secondary. • Dafaa will cover every high-school subject; mathematics comes next. Why Dafaa? • 100% free, no ads. • No account needed: type your name, pick your year and stream, and start. • Works offline once a unit is downloaded. Dafaa is an independent app made by Majal. Its content is original. It is not a government app and does not represent any government entity.
