The current IB Biology course, first examined in 2025, is organised into four themes: unity and diversity, form and function, interaction and interdependence, and continuity and change. HL adds depth across every theme.
- Paper 1: multiple-choice questions plus data-based questions
- Paper 2: data-based and extended-response questions
- Internal assessment: the scientific investigation, from research question to evaluation
- Command terms, mark-scheme language and timed past papers
Lessons start from HK$120/hour, and IB tutoring typically runs HK$400-800/hour; we confirm your exact rate in the free trial lesson.
