EduNinja helps IB Biology learners organise revision around the course they actually study. Choose an SL or HL route, browse the syllabus map, and open available learning resources and topic questions. The question bank includes a Water-topic starting point and answer or mark guidance for reviewing responses.
The service is browser-based at https://eduninja.pro. Biology HL question practice can be found at https://eduninja.pro/ib/biology/hl/question-bank. Material availability is shown within each course; not every subject or syllabus topic is presented as complete.
IB Biology revision requires matching the course level and syllabus topic before practising. EduNinja was built to connect those steps in one browser-based learning route: choose the course, find a topic and work through the questions that are currently available.
