Drugs — IGCSE Biology (0970) questions by topic
Drugs questions define what a drug actually is as a substance that modifies chemical reactions in the body, match antibiotic properties to correct sentence endings, choose the accurate statement about how antibiotics act on bacteria versus viruses, and describe antibiotics' effect precisely rather than in general terms.
Identify, choose, draw, calculate and state lead just 5 real questions, the smallest set on this page, worth 1 to 6 marks from 2023 to 2025 papers. Because antibiotic questions are frequently repeated with only the wording changed, submitting each answer for instant marking quickly confirms whether the bacteria-only, not-viruses distinction has been genuinely understood rather than half-remembered.
