Gradarius makes learning and teaching Calculus more engaging, efficient and effective.

Gradarius is an intelligent software platform that provides students with immediate feedback on every step of the solution and instructors with data and insights about the thinking behind each student solution.

By combining data analytics with symbolic computational algorithms, Gradarius is the only Calculus Learning Platform that enables an instructor to readily observe areas of mastery and concern for every student in the class in an in-depth manner. Using dashboards and reports, an instructor can see the specific steps a student entered to solve a problem, along with the feedback provided by Gradarius. The instructor can readily see a snapshot of each student’s knowledge state, illustrating a student’s logic path for solving a particular problem or set of problems.

Today’s students need to learn when it fits their schedule. Gradarius is available 24 hours a day, 7 days week and can be accessed on a desktop PC, as well as mobile devices. Cloud-based, Gradarius is available on a subscription basis and can be integrated with the leading academic Learning Management Systems used by universities, colleges and high schools.
