Calculator policy
Use only calculators on the HKEAA Approved List, bearing the 'H.K.E.A.A. APPROVED' (or older 'H.K.E.A. APPROVED') label. Programmable scientific models (e.g. Casio fx-50FH II, fx-3650P II) are allowed, and you MAY keep your own formulas/programs stored in memory — HKDSE does not require you to clear it. Graphic-display (graphing) and CAS/symbolic calculators are not on the approved list and must not be used.

Mistakes
- In HKDSE Biology Paper 1B, you are faced with a challenging task: securing 84 marks in just 110 minutes. This gives you exactly 1.3 minutes per mark. However, to allow a safety buffer for review and complex data analysis, top-scoring candidates always practice the 1.2-minute rule. This means a 5-mark structured question must be completed within 6 minutes, and the 11-mark extended essay should take no more than 13 minutes. When the exam begins, do not dive blindly into writing. Spend the first 2 minutes scanning the entire paper to assess the difficulty of the experimental design questions and the topic of the comparative essay. Write down quick, high-level keywords or formulas next to the questions immediately. If you encounter a tricky biological pathway or a complex genetic pedigree, do not stall. Move on and protect your time; the low-hanging marks of the later questions are waiting for you.
