Control and verification works based on O.S. Gabrielyan’s 10th-grade chemistry curriculum focus on evaluating knowledge across organic chemistry, fundamental principles, and chemical processes through structured Part A (tests) and Part B (open-ended) tasks. Utilizing GDZ (ready-made homework) for this material is most effective as a self-check tool to verify reaction equations and chemical calculations rather than for simple copying.
