Topics

In this document, the NChB Academic Committee establishes a conditional 'syllabus' for the tasks of the qualifying and final rounds. The committee considers the most natural way to organize the material is by comparing different stages and grading by leagues. Our collection of topics is partially based on the QazChO syllabus. Any of the topics listed below may appear in the tasks of the corresponding round and league without additional theoretical introduction, so participants are recommended to be familiar with them. However, tasks may include topics beyond the syllabus.

Junior League

Includes the school curriculum for chemistry and mathematics for secondary schools up to and including grade 9.
