1. Read the Question Twice | 审题两遍

Many marks are lost because candidates misread key words such as “hence”, “exact value”, “to 3 significant figures”, or “positive root”. Read the whole question carefully before you start. Identify what is given, what is asked, and any constraints. Then read again to confirm you have not missed a condition.

许多失分是因为看错关键词，如“hence（由此）”“exact value（精确值）”“to 3 significant figures（保留三位有效数字）”或“positive root（正根）”。动笔前先仔细读完整道题，分清已知条件、待求目标和限制条件。然后再读一遍，确认没有遗漏任何条件。

2. Plan Your Time | 规划答题时间

Divide your total exam time by the number of marks to set a pace. For example, if you have 120 minutes for 100 marks, allow roughly 1.2 minutes per mark. Allocate a few extra minutes for high-mark questions and reserve 5–10 minutes at the end for checking. Use a watch and keep moving — never spend more than half the marks’ worth of time on a single question.

将总考试时间按分值分配：例如120分钟、100分，则每题约1.2分钟。高分值题多预留一些时间，并在最后留出5–10分钟检查。戴手表并持续前进——切忌在一道题上花费超过其分值一半对应的时间。

If you get stuck, write a note and move on. Completing the easier questions first builds momentum and guarantees marks.

如果卡住，标记后先跳过。先完成容易的题能积累势头并确保得分。

3. Choose a Smart Question Order | 选择聪明的做题顺序

Not every paper needs to be answered in numerical order. Scan the whole paper first. Start with questions you are confident about, then tackle more challenging ones. This reduces anxiety and ensures you do not lose easy marks because of running out of time at the end.

并非每张试卷都必须按顺序作答。先通览全卷，从最有把握的题做起，再挑战难题。这样可以降低焦虑，也避免因最后时间不够而丢失容易的分数。

4. Show Full Working Steps | 展示完整步骤

Mathematics exams award method marks. Even if your final answer is wrong, a clear method can earn partial credit. Write every step logically: state the formula, substitute values, simplify, and give the final answer with units or correct rounding. Use an equals sign at the beginning of each new line.

数学考试有方法分。即使最终答案错误，清晰的思路也能获得部分分数。按逻辑写出每一步：写出公式、代入数值、化简、给出带单位或正确舍入的最终答案。每次换行时在行首写等号。

For example, when solving 2x + 5 = 13, show:

2x + 5 = 13 → 2x = 8 → x = 4

This simple chain shows the examiner exactly how you obtained the answer.

例如解2x + 5 = 13，写出：2x + 5 = 13 → 2x = 8 → x = 4。这串简单等式向考官清晰展示你如何得到答案。

5. Master Formula Recall | 熟练公式记忆

You should know the essential formulas by heart, but also know which formulas are given on the exam’s formula sheet. In the final days, make a one-page summary of tricky formulas: integration rules, trig identities, quadratic formula, log laws, and differentiation rules. Review it daily and use it to solve quick practice problems.

必须熟记核心公式，同时知道哪些公式在考试公式手册中。冲刺阶段，用一页纸总结易混淆的公式：积分规则、三角恒等式、二次方程求根公式、对数定律、微分法则。每天复习并用于快速练习。

When using a formula, always write it down first. This not only earns a method mark, but also helps you avoid careless substitution errors.

使用公式时先把公式写出来。这既能获得方法分，也能帮助你避免粗心的代入错误。

---

6. Verify Your Calculations | 验证你的计算

After obtaining an answer, check whether it satisfies the original conditions. For equations, substitute the solution back into the left and right sides. For word problems, verify the units and the reasonableness of the magnitude. For example, if a length is negative, something is wrong.

得到答案后，检查它是否满足原题条件。解方程时，把答案代回等号两边验证。应用题中，确认单位与数值大小是否合理。例如长度为负数，那肯定有误。

Use estimation as a quick check: if 17 × 29 is close to 493, but your calculation gives 4,930, a decimal point has slipped. Catching this in the exam saves precious marks.

用估算快速检查：如果17 × 29的结果约为493，而你的计算得到4,930，那是小数点错了。考试中及时发现就能保住分数。

7. Deal with Difficult Questions Strategically | 战略性应对难题

When you meet a hard question, do not panic. Write down any formula or related theorem you know. Sometimes earning the first method mark is enough to unlock the problem. Break the question into smaller parts and solve each part separately. If a part asks for “hence or otherwise”, you can use any valid method to get the answer.

遇到难题时不要慌张。先写下任何相关公式或定理，有时拿到第一个方法分就能打开思路。把问题拆成小部分，分别解决。如果题目要求“hence or otherwise（由此或另法）”，你可以使用任何有效方法求解。

For multiple-choice questions, use elimination: cross out options that are clearly wrong, then test remaining candidates with a quick substitution.

对于选择题，使用排除法：划掉明显错误的选项，再对剩余选项做快速代入检验。

---

8. Draw Diagrams and Graphs | 画图与图形

For geometry, vector, and calculus questions, a clear diagram helps you visualize relationships. Many students skip drawing because they think it wastes time, but a quick sketch can reveal solutions that are otherwise hidden. Mark angles, side lengths, coordinates, and intercepts.

对于几何、向量和微积分题，清晰的图能帮助你直观理解关系。很多学生认为画图浪费时间而不画，但快速草图能暴露原本隐藏的解法。标出角度、边长、坐标和截距。

When graphing a function, always show the axes, scale, turning points, asymptotes, and intersections. Use a pencil so you can correct easily.

画函数图像时，务必画出坐标轴、比例、极值点、渐近线和交点。用铅笔绘制，便于修改。

9. Write Cleanly and Follow Format | 书写整洁、遵循格式

Examiners find it easier to award marks when your working is legible. Write in dark blue or black pen for the final answer, and use pencil for diagrams. Leave enough space between lines. Number your answers clearly if you skip around in the paper.

书写清晰易读，考官更容易给分。最终答案用深蓝或黑色笔，图形用铅笔。行间留足空隙。如果跳着做题，请清晰标注题号。

Use the correct notation: write vectors in bold or with an arrow, put units in brackets, and use an appropriate number of decimal places. If the question states “give your answer in terms of π”, do not write a decimal approximation.

使用正确的符号：向量用粗体或箭头，单位加括号，答案按精度要求保留位数。如果题目要求“以π的形式给出答案”，请不要写成小数近似值。

---

10. Mind Your Calculator and Units | 注意计算器与单位

Before the exam, check your calculator’s battery and mode. Set it to degrees or radians according to the question. When a question mixes units (e.g., meters and centimeters), convert all values to the same unit before calculating. Write the unit in your final answer and double-check that it is the one requested.

考试前检查计算器电池和模式。根据题目要求设为角度制或弧度制。当题目包含混合单位（如米和厘米）时，先统一单位再计算。在最终答案中写上单位，并再次确认是题目要求的单位。

For angles, pay attention to the domain: if θ lies in [0°, 180°], your answer should not be −30° or 300°.

对于角度，注意定义域：如果θ在[0°, 180°]内，答案不应是−30°或300°。

---

11. Review and Catch Errors | 复查并捕捉错误

In the final minutes, do not sit idle. Re-read each answer critically. Check for silly mistakes: sign errors, powers miscalculated, fractions inverted, or missing ± when taking a square root. Verify that all pages are answered and that your name and candidate number are on the paper.

最后几分钟不要空坐。带着批判眼光重读每道答案。检查低级错误：符号错、指数算错、分数倒置、开平方时漏写±。确认所有页面都已作答，且姓名和考号已填写。

For double-checking, try a different method to solve the same problem if time allows. For example, if you used the quadratic formula, verify by factoring the expression. Two different methods agreeing strongly indicate correctness.

如果时间允许，用不同方法检查同一道题。例如用二次公式求解后，再尝试因式分解验证。两种方法得到一致结果，正确性就很高。

---

12. Stay Calm and Confident | 保持冷静与自信

Your mindset is as important as your technique. When you enter the exam hall, take a deep breath and remind yourself that you have prepared. If your heart races, pause for a few seconds and read a familiar question to regain control. Remember that the exam is about showing what you know — not about perfection.

心态与技巧同样重要。进入考场时深呼吸，提醒自己已经做好准备。如果心跳加速，停几秒，读一道熟悉的题目来恢复掌控。记住考试是展示你所学——而非追求完美。
