Czechia Chemistry Olympiad - Category D (for junior middle school)
Chemická olympiáda
Category D is the junior category of the Czech Chemistry Olympiad, targeting middle-school students (~age 15, typically Grade 9).
Unlike Categories A and E, Category D does not have a national round — the competition runs through school and district/regional levels only.
Exam content covers introductory chemistry: basic concepts, simple reactions, atomic structure, and qualitative observations. Category D is the entry point for younger students into the Czech olympiad system.
