学习常见前后缀：cyto- 表示细胞，trans- 表示跨过，lysis 表示分解。
10. Time Management Strategies | 时间管理策略
Each exam paper has a recommended time per mark, usually about 1.5 minutes per mark. For a 90-mark paper lasting 2 hours, you have approximately 80 seconds per mark. Use this to allocate your time across the paper.
每份试卷都有建议的每分用时，通常每分约 1.5 分钟。对于一份 90 分、时长 2 小时的试卷，你大约每分有 80 秒。以此分配整份试卷的时间。
Start with questions you are confident about to build momentum.
先做你有把握的题目，以建立节奏。
For extended response questions, spend 2–3 minutes planning before writing.
对于扩展回答题，写作前花 2 到 3 分钟列提纲。
Leave 5–10 minutes at the end to check calculations and unit conversions.
最后留出 5 到 10 分钟检查计算和单位换算。
A suggested approach for a 2-hour paper:
一份 2 小时试卷的建议答题策略：
| Section 部分 |
Time Allocation 时间分配 |
| Multiple choice (15 marks) 选择题（15 分） |
20 minutes 20 分钟 |
| Short answer (40 marks) 简答题（40 分） |
50 minutes 50 分钟 |
| Extended response (25 marks) 扩展回答（25 分） |
35 minutes 35 分钟 |
| Checking 检查 |
15 minutes 15 分钟 |
11. Common Mistakes to Avoid | 常见错误及避免方法
Many students lose marks due to avoidable errors. In biology, imprecise language is a major issue. Writing 'DNA makes protein' instead of 'DNA codes for the sequence of amino acids in a protein' demonstrates a lack of precision. Similarly, forgetting to include units in calculations or mixing up terms like 'diffusion' and 'osmosis' can be costly.
许多学生因为可以避免的错误而丢分。在生物学科中，语言不精确是一个大问题。写“DNA 制造蛋白质”而不是“DNA 编码蛋白质中氨基酸的序列”显示出缺乏精确性。同样，忘记在计算中写单位或混淆“扩散”和“渗透”等术语会造成较大损失。
Always define variables before using them in statistical tests.
在统计检验中使用变量之前，先定义变量。
In drawings, use clear, unbroken lines for cell walls and membranes.
在绘图时，用清晰连续的线条绘制细胞壁和细胞膜。
Practise past papers under timed conditions to identify weak areas.
在计时条件下做真题，找出薄弱环节。
