Major Human Diseases Study Guide: NEB 12 Biology

Seven-session plan

Turn Typhoid, Tuberculosis, HIV, Cholera, Influenza, Hepatitis and Candidiasis into retrievable knowledge

Major human diseases differ in pathogen, transmission, target organs, incubation, prevention and treatment. Safe answers compare them systematically and use current public-health guidance rather than treating all infections alike.

1. Map prerequisites and definitions.
2. Derive or justify the main relation: Build a matrix of agent→route→key effects→prevention→diagnostic approach→treatment principle; vaccination and antimicrobial availability differ by disease.
3. Redraw diagrams from memory.
4. Study this worked checkpoint: Cholera prevention emphasizes safe water and sanitation, tuberculosis control requires testing and a complete multidrug regimen, and HIV is managed with antiretroviral therapy rather than antibiotics.
5. Mix conceptual and numerical questions.
6. Complete a timed closed-book set.
7. Retest only the first wrong decision in each answer.

Use contrast tables and error cards

Place easily confused ideas side by side. Write what stays fixed, what changes, the governing equation and the observable consequence. One high-value warning is: Confusing virus, bacterium and fungus, recommending antibiotics for viral disease, presenting symptoms as diagnosis, or stigmatizing affected people.

Use spaced retrieval: ten minutes today, a closed-book test tomorrow and a mixed review after one week. Explain every graph or diagram aloud before using algebra.

NEB answer method

Model → evidence → equation → check

First identify the system and what the question asks. Label the diagram, apparatus or reaction with SI quantities, then state the principle before selecting an equation. Solve symbolically where possible and check units, limiting cases and chemical or physical meaning.

Make the idea concrete in Nepal

Connect the model to a school laboratory, household technology, health, environment, energy or local material. The example should clarify the science rather than merely mention a place. Compare a prediction with an observation and record uncertainty.
