🧪 Chemistry (Grades 8-11)

**Chemistry (grades 8–11)** introduces substances, reactions, atomic structure, and the periodic table. This course helps you understand why reactions happen, not memorize equations by rote. You will study molar mass, stoichiometry, acids and bases, redox, and school-level organic chemistry. Problems include clear reasoning for each step. After the course tests and exams feel more predictable, and links to biology and ecology become clearer.
