OSC has been producing IB Revision Guides since 2002 and we now publish more IBDP specific material than anyone else in the world. We know the importance of revision and review and want to be able to support all IBDP students with our expertise and experience.

The rigorous and balanced learning values of a global curriculum are reflected in the content and structure of OSC revision guides. They offer complete coverage of the IB syllabus, emphasising active revision and review at every stage, with diagrams, exercises, illustrations, examples and exam tips that enable students to absorb and retain vital information in their subject, whatever their learning style.

“We just finished our Biology HL exams, and I wanted to thank you very much for writing such a tremendous IB Biology guide. There are many good guides out there, but I must say that yours is by far the best – it’s got everything you need to know, not too much, and not too little. Your guide made it a lot easier for us in the exam, especially in the weeks leading up to them.” – IB Student
