Unsure about how you will do in your oral? With marksy you can practice your oral assesments, get grade predictions, follow ups, and feedback by speaking out loud, uploading an audio or transcript.
Open workflowLearn
Ditch your textbooks. You can learn official IB content with marksy. Our online textbooks cover official IB content and have interactive simulations and quizes that textbooks don't.
Open workflowPlay
Some complex topics require visualizations to understand. We have hundreds of simulations for many IB concepts where you can manually tweak parameters to understand a concept better.
Open workflowPast Papers
Everyone has past papers, but can you actually grade yourself as an examiner? We trained an AI that understands the markscheme and grades your work on official IB past papers.
