About this app

XobéBook, your app for practicing science in high school.

Designed initially for students in Senegal and now open to all French-speaking high school students, regardless of your academic track (S, L, ES, etc.). The content adapts to your grade level. You'll find math, physics, and chemistry exercises organized by subject, grade level, and lesson: 10th, 11th, and 12th grade.

WHAT YOU CAN DO

• Browse exercises categorized by subject and lesson, with clear instructions on each page.

• Filter by complexity (Easy, Medium, Hard, Advanced), relevance, and answer key status.

• Sort by newest, most viewed, most completed, most relevant, most complex, most liked, or most shared.

• Work with thematic handouts that group exercises around a single topic to review a chapter in one go.

• Consult supplementary course materials when the exercise offers them: a PDF, an external link, or a video. These resources are optional, not required.

• Try it first, look later: the solution opens after you've spent some time on the problem. You tackle the exercise before seeing the solution.

• Filter exercises with verified solutions: solutions are added and validated progressively. The filter allows you to target what's already ready or to work on a problem on your own.

• Share an exercise with a classmate in two steps, and report a problem if you spot one.

WHO IS IT FOR?

High school students in grades 10, 11, and 12, all tracks (Science, Literature, Economics & Social Sciences, etc.): prepare for an assignment, aim for the baccalaureate exam, catch up on a chapter, or practice regularly.

Initially designed for Senegal, this tool remains relevant for any French-speaking student following a similar curriculum.
