As far as I can recall, the IB program starts in grade 10. Students complete math 10, 20 in one year, math 30, 31 the next year. They have options in terms of how they plan their program and can complete full IB or partial IB. There is a research project that must be completed. There is no point in knowing what things are on the tests because the exams typically require problem analysis rather than regurgitation.
