SATMath - Adaptive Digital SAT Math Testing & Practice Platform

We developed a next-generation EdTech platform that mirrors the official Digital SAT Math exam while supporting both classroom learning and independent study. The system offers adaptive and regular test modes, personalized dashboards for different user roles, real-time analytics, and a rich practice module — all within a subscription-based model.

- Build an adaptive test engine that simulates real Digital SAT logic
- Enable both assigned and self-paced testing with different flows
- Support multiple user types (admins, teachers, students, accountants) with role-based dashboards
- Deliver a seamless, secure equation editor for student-produced responses
- Protect proprietary educational content from being copied or misused
- Implement robust payment handling and plan-based access control

We created a full-featured web platform that includes:
- Adaptive & Regular Testing: Adaptive tests adjust difficulty between modules based on student performance; regular tests are static and assignable by teachers.
- SAT-Like Interface: On-screen calculator, timer, reference sheets, and review panel match official SAT UX.
- Practice Problems Mode: Students can drill into topics (e.g., Algebra, Geometry) with instant feedback and difficulty-based tracking.
- Role-Based Dashboards: Separate views for Superadmins, Teachers, Students, and Accountants with specific permissions and tools.
- Subscription System: Plan-based feature access (Basic, Advanced, Premium) with PayPal integration and real-time access control.
- CMS Features for Admins: Manage content pages, banners, pricing plans, SEO, and system settings through a custom backend.
- Security Features: Prevent screenshotting/copying with layered frontend and backend protections.

The platform is now live and serving both educators and students. It provides a reliable, modern, and secure environment for preparing for the Digital SAT — helping students master skills and educators manage learning at scale.

“They delivered exactly what we envisioned — a smooth SAT testing platform that works flawlessly for both self-paced learners and classroom environments. The adaptive logic, role-based dashboards, and user experience are top-notch. Their frontend skills, backend architecture, and problem-solving mindset were essential to making it all work.” - Professor, SAT Math
