OSC Study includes official IB exams for Maths A&A, Maths A&I, Biology, Chemistry, and Physics.

These exams come directly from the International Baccalaureate.

OSC Study also includes additional OSC practice exams for Maths A&A and Maths A&I. We added these because the two Maths courses are so new, meaning there are only a few exams the International Baccalaureate currently has available.

OSC practice exams are written by leading authors, ensuring they authentically replicate official IB exams.

The number of official IB exams and OSC practice exams per subject, as well as the number of subjects covered with official IB exams, are increasing continuously. As new content becomes available, we will add them to your account as free updates.
