Odisha BSE HSC General Science study guide
Odisha BSE HSC General Science · Work through your exam, one topic at a time.
This independent study page supports candidates preparing for the General Science component of the Odisha Board of Secondary Education High School Certificate (HSC) examination, the Class X school-leaving credential in Odisha. The Board describes itself as a body corporate constituted under the Odisha Secondary Education Act, 1953; it regulates secondary education in the state, examines candidates who complete a prescribed course of study and awards certificates to successful candidates. This page has no official connection with the Board. Start with the Board's Class X subject-wise syllabus and its document titled "Pattern of Question with Distribution of Marks for Class IX & X (Annual HSC Examination, 2026)." The retrieved Board homepage does not list the General Science topic breakdown, paper duration, maximum marks or pass mark, so confirm those on the current syllabus and pattern PDFs rather than relying on older figures. The Odisha BSE HSC General Science study guide has 4 sections and about 1,487 words.
01Physics: Light, Electricity and Magnetism
Physics in the Odisha HSC General Science paper tests light - reflection, refraction, lenses and the human eye - together with electricity, magnetic effects of current and sources of energy. Numericals are short, but sign and unit errors are heavily penalised, so state the sign convention you use before substituting values.
410 words, about 2 min02Chemistry: Reactions, Acids–Bases, Metals and Carbon
Chemistry in the HSC paper covers chemical reactions and equations, acids–bases–salts, metals and non-metals, carbon compounds and periodic classification. Expect balanced equations with state symbols, ion identification from tests, and predictions based on the reactivity series.
353 words, about 2 min03Biology: Life Processes, Coordination and Heredity
Biology tests life processes - nutrition, respiration, transport and excretion - plus control and coordination, reproduction and heredity. Answers must name the structure, give its function and, where asked, a ratio with the reasoning shown.
371 words, about 2 min04Environmental Science: Ecosystems, Pollution and Resources
Environmental Science covers ecosystems and energy flow, pollution and atmospheric change, and management of natural resources such as forests, water, coal and petroleum. Answers should use ecological terms precisely rather than everyday wording.
