What students value in a connected study workspace.

The explanation helps me understand why an answer earns marks, not just what the final answer is.

IB Chemistry student
IB Diploma · HL

The syllabus map helps me see what I have covered and what I still need to practise before the exam.

A-Level Biology student
CAIE · A-Level

Before mocks, I can focus on my weak topics instead of working through random questions.

IGCSE Maths student
Edexcel · IGCSE

I can learn a topic, practise questions on it and then add the right questions to a test.

A-Level Chemistry student
CAIE · A-Level

When I get a question wrong, I can go back to the exact topic instead of guessing what to revise.

FAQ

EduNinja is built for IB Diploma, A-Level and IGCSE. Subject availability depends on the curriculum and exam board you choose, with supported combinations across Biology, Chemistry, Physics, Mathematics, Economics, Business, Psychology, ESS and more.

Yes. You choose your curriculum, exam board, subject and level first. The Library then keeps its knowledge tree, concepts, questions and documents organised around that same course structure, so you can work topic by topic instead of searching through generic revision material.

Question Bank is where you practise exam-style questions. Mastery turns the knowledge tree into a roadmap of what to learn, practise and review. Concept explains what the syllabus expects and includes formal exam analysis from mapped paper evidence, while Documents keeps related study resources alongside the course.

Learn moves through focused explanation cards one step at a time. Practice presents one question at a time with Check and I don’t know actions, guided feedback, retry support and an end-of-session report that points you back to the areas that need attention.

Yes. Select questions from the Question Bank, review the set in Test Builder, give the paper a useful title, and generate a question paper and answer key as PDFs for focused exam practice.

You can explore the course structure and use a limited monthly amount of Learn and Practice before upgrading. Premium unlocks full access to question banks, guided practice, answers, progress tracking and the study resources included with your plan.
