NEB Class 12 Biology study guide
NEB Class 12 Biology · Work through your exam, one topic at a time.
NEB Grade 12 Biology (कक्षा १२ जीवविज्ञान) is a subject examination of the National Examinations Board (राष्ट्रिय परीक्षा बोर्ड), Sanothimi, Bhaktapur, Nepal's government examinations authority, which administers Grade 12 (कक्षा १२) papers including Biology. It is taken by students who have completed Grade 11 science study and need a Grade 12 subject result for higher study, particularly for BSc, agriculture, forestry, nursing, pharmacy, medicine and veterinary pathways. The paper assesses the Biology syllabus approved for Grade 12, and NEB separately publishes a practical work implementation directive (व्यावहारिक अभ्यास कार्यान्वयन निर्देशिका, २०८३), so candidates should expect laboratory-based assessment alongside the theory paper. Preparation should be built directly from the NEB-approved curriculum and the Assessment Framework for Grade 12, which is published on the NEB website, together with the downloadable model question papers (नमुना प्रश्नपत्रहरू). Candidates should also check the annual examination routine for the academic session and the practical directive before planning revision. This page is an independent study resource; it is not affiliated with or endorsed by NEB, and any figure such as item count, full marks, duration or pass mark should be confirmed against the current NEB curriculum and Assessment Framework rather than from third-party summaries. Topics on this exam: Biology (Grade 12) - content domains not enumerated in source. The NEB Class 12 Biology study guide has 1 section and about 430 words.
01Grade 12 Biology: Integrated Syllabus - Genetics, Molecular Biology, Biotechnology and Ecology
This section covers the Grade 12 Biology paper. It tests a combined botany–zoology syllabus built around heredity, molecular biology, biotechnology, evolution, ecology and human health, and it rewards precise mechanism over memorised labels. Expect questions that ask you to explain a process step by step, interpret a cross or a population, and justify conclusions. Genetics: Mendel's laws.

- Practice questionsWhich process directly produces the ATP used by the contractile proteins during muscle contraction?
- FlashcardsBinary fission. Asexual reproduction in which a parent cell divides into two identical daughter cells, typical of bacteria and amoeba; no meiosis or gamete fusion is involved.
- Cheat sheetReproduction: asexual (binary fission, budding, fragmentation, spore formation, vegetative propagation) produces genetically identical offspring; sexual reproduction involves meiosis and syngamy and generates variation.
- Key termsTaxonomy. The branch of biology that identifies, names, and classifies living organisms into hierarchical groups such as kingdom, phylum, class, order, family, genus, and species, based on shared characteristics and evolutionary relationships.
- Study planDefine and distinguish the core terminology of the heaviest units (genetics, molecular biology, reproduction) using your own one-line definitions for at least 60 terms.
- Common mistakesCandidates memorise the abstract definition and treat the example as optional decoration, not realising NEB marking schemes allocate separate marks for definition and for a named example with a brief explanation.
