The system automatically checks the solution and provides detailed feedback on each step, including hints, diagnosis of common errors, and personalized recommendations for further learning and teaching.FullProof is suitable for both classroom work and homework.

The system informs the teacher of the student's activities and the difficulties encountered in the classroom, and does so on an ongoing and immediate basis, without the need to examine lessons or tests.
