Alps helps every computer science student reach mastery in a regular class, K-12 through college. Teachers choose their curricula: open textbooks such as CSAwesome, Mobile CSP and Think Python, licensed publisher titles, their own material, or a mix in one class. Students read, run code and practice in the browser, in Java, Python, C++, SQL and Snap! blocks. There is nothing to install.

What teachers get
• Adaptive practice: more than 10,000 leveled, auto-graded problems, and one-click differentiated assignments by mastery and engagement.
• Pathfinder: help, not answers, the moment a student is stuck: a scaffold, subgoals, a hint, then a Mixed Up Code puzzle. The teacher sees every step.
• Grading: code and questions auto-graded with unit tests, and open responses graded by AI against the teacher's rubric. The teacher can review and change any score.
• Live activity and class insights: who is stuck right now, and the wrong answers and errors the class shares, so class time goes where it helps most.
• Gradebook: every student and assignment in one grid.
