Frequently Asked Questions

MockSphere is a comprehensive educational platform focused on AI/ML, mathematics, and coding education. We provide interactive problems, learning materials, certifications, and knowledge graphs to help learners master technical skills at their own pace. Educators can also create problems and earn revenue by sharing them with the community. Parents can create family connections to monitor their children's progress.

MockSphere is designed for learners of all levels - from K-12 students to professionals. Whether you're just starting your journey in AI/ML or looking to advance your existing skills, our platform has resources tailored to your needs.

We offer both free and premium content. Many problems and learning materials are available for free. Premium subscriptions unlock advanced features, exclusive content, and certifications. Check our subscriptions page for detailed pricing.

Creators are educators and experts who publish problems for classrooms, teams, or the broader community. Creators can organize learners into groups (like classes, company teams, or recruitment cohorts) and assign problems directly to those groups.

Teachers (K‑12 or higher‑ed), interviewers/recruiters, or users with strong track records (e.g., 10,000+ points) can apply. We review each application to ensure quality and safety for learners.

Apply to become a Creator

Creators earn based on Premium members' successful problem submissions. We convert engagement into points, apply a monthly per‑learner cap (10 points per learner per creator), and share a 30–50% revenue pool with creators. Pricing is platform‑controlled, so creators don't need to set prices per problem.

We keep the exact weights and exchange rates private while communicating the overall revenue‑share range for fairness and simplicity.

Groups are private spaces you create for a classroom, company team, or recruitment cohort. Members join with an invite code. When you assign a problem to a group, it’s available to the members of that group. If you don’t assign a problem to any group, it’s available across the platform.

Yes. When Premium members in your groups successfully solve your problems, those submissions count toward your monthly points and revenue share. We apply safeguards like per‑learner caps to keep things fair.

Each group has a unique invite code. Share it with your learners or teammates so they can join. You can create as many groups as you need for classes, projects, or hiring cohorts.
