XobéBook
Sobel Tech
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, whether in the science or humanities track. The content adapts to your grade level. You'll find math, physics, and chemistry exercises, lessons, and handouts for grades 10, 11, and 12.
WHAT YOU CAN DO
• Browse solved exercises from your grade, with the problem statement displayed full screen, page by page.
• Take a picture of an exercise (or copy an excerpt from the problem statement) to find similar exercises that have already been solved. Nothing similar? Request the solution, and you'll be notified when it's ready.
• Filter by solution status, complexity (Easy, Medium, Hard, Advanced), importance (Bonus, Practice, Recommended, Essential), subject, or exercises you've already completed.
• Sort by newest, most viewed, most discussed, most important, most complex, most liked, or most shared.
• Search first, then get the answer key: you start the exercise, work through the problem, and then the answer key appears. No answer key yet? Request it.
• Review with your class lessons, subject by subject: content broken down into sections, with real-life examples, definitions, and graphs. Track your progress (in progress, completed, under review). Relevant lessons are readily available from within an exercise.
• Work on complete assignments and handouts to review an entire chapter.
• Share: comment on an exercise, reply to and like other users' comments, or ask the team a private question.
• Track your progress: completed exercises, views, time spent per subject, and badges to earn.
• Save and share: bookmark an exercise, share it with a classmate, or report a problem if you spot one.
• Get notified when a search is successful, a solution is ready, or you receive a reply. You can manage notifications from your profile.
WHO IS IT FOR?
High school students in grades 10, 11, and 12, in both science and humanities tracks: 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.
