Problem
IB Mathematics students often lack centralized, curriculum‑aligned resources that provide detailed, step‑by‑step solutions for past exam questions across both Analysis & Approaches (AA) and Applications & Interpretation (AI) courses. Without such resources, learners must piece together disparate notes, leading to inefficient study sessions and gaps in exam readiness.
Solution
Prime Sums delivers a subscription‑based, cloud‑hosted library that aggregates written markschemes and high‑definition video walkthroughs for every IB Mathematics question from both AA and AI tracks, at Standard and Higher Levels. The platform indexes content by exam year and topic, enabling precise retrieval of relevant solutions. Each solution is authored by former top‑scoring IB candidates, ensuring methodological rigor and alignment with the latest IB syllabus. Interactive video explanations complement textual steps, reinforcing conceptual understanding and problem‑solving techniques. A responsive web interface supports seamless navigation on desktop and mobile devices, while built‑in search filters accelerate targeted revision. The service also offers a limited free tier with sample questions, allowing prospective users to evaluate content quality before upgrading.
Target Audience
The primary users are current IB Mathematics students (AA and AI, Standard and Higher Level) and secondary educators seeking curriculum‑aligned solution resources for classroom instruction and exam preparation.
