Mission
Help every matric learner practise beyond recall, turning difficult concepts into confident understanding through accurate, exam-worthy questions and marking.
Problem
Over 900,000 learners sat the NSC in 2025, but quality exam practice depends on access to tutors, well-stocked schools and teachers with time to mark. Free past papers are static, so many learners never face the unfamiliar, higher-order questions that increasingly appear in NSC and IEB papers.
Solution
Cortex generates new exam-style questions, including unfamiliar higher-order scenarios, for any topic a Grade 12 learner picks. Every question comes with mark allocations, an interactive mark scheme and a model answer, so learners see exactly how marks are earned. Tutors can generate worksheets in bulk. Our Grade 12 STEM CATALOGUE Practice Room is live, and a 50-learner pilot is underway.
