The world leader in IB revision and review 

OSC is a network of hundreds of IB teachers, co-ordinated by a professional management team. We visit schools, teach on vacation courses and create IB review content, supporting tens of thousands of IB students each year. 

We are honoured by the level of trust that is placed in us by parents, students and the wider IB community. For over 25 years, we have been dedicated to offering high quality IB support built upon a strong academic foundation. This is recognised in our British Accreditation Council (BAC) report

Over 70% of our students join OSC because a friend, family member or teacher has recommended they attend. What they tell us when they leave truly inspires us ...

Built on strong academic foundations

 

Design

The academic structure of each OSC course has been developed in recognition of the relevant stage of the students' path through the IBDP and is based on solid pedagogical expertise.

Teachers

We employ hundreds of highly experienced IBDP teachers – most have been examiners. They understand students' learning and have the expertise to support diverse needs.

Content

Our Teachers and Authors create their classes and content based around their vast experience and the unique needs of students. They are up-to-date with syllabus changes.

Size

We are both large and small. The large number of students allows us to offer many parallel classes. But each class is small. Taken together, this allows individual needs to be met.
