IBDP exam, that is, international bachelor degree diploma course. It is a pre-university course for high school students in grades 1 1 and 12. Different from other international preparatory courses, IB is independent and has its own independent curriculum system, so IB courses all over the world are conducted according to the same syllabus and take a unified graduation selection examination.

After completing the two-year IB course, students will take the exam in May every year, and those who pass the exam can get the IB international diploma. Most American universities are accredited, including Ivy League schools. IB curriculum is not based on the curriculum system of any country in the world, but is self-contained, which widely absorbs the advantages of mainstream curriculum systems in many developed countries and covers its main core contents.
