A-Level经济试题既考察学生的应试能力,也是一大学科知识测试,经济学是A-level的一门硬课,想要拿到A可不容易。而且经济学本身,理解起来就很有难度,或许我们可以在课堂之外,通过更轻松的方式吃透经济学!小编今天给大家介绍的就是exam-smart tips,希望能帮助同学们A-Level考试夺得高分!
技巧1-事件的影响
在不同的经济领域,学生们经常被要求评估事件对某件事的影响。
技巧2-关注经济分析
写经济essay的时候,时间总是紧张的。那么知道内容比例的划分就尤为重要,解释content占多少,简洁的explanation占多少。
有一条70/30法则。两个例子:
Theory of CA包含很有价值的经济分析,学生应该解释它的假想条件,比较机会成本比率,得出贸易可以获得什么。
Material SOL要求具体的经济分析,包括实际GCP与名义上的GDP数字、收入分配、按PPP计算的GDP。
技巧3-合理性检查
非常有用,但也经常被忽视的一点。意思就是看一下自己的topic sentences,是否用最直接的方式回答了问题。有时候,我们有些段落可能是用来介绍背景信息但却没有直接回答问题。
例如
Explain why the price of fuel tends to be more volatile than other secondary products. (10m)
Topic Sentence (Version 1): The PED of fuel is affected by a number of factors, including its degree of necessity. Supply of fuel is also affected by a number of different factors.
Topic Sentence (Version 2): Demand for fuel is price-inelastic due to its nature as a necessity. Supply may also fluctuate given unstable conditions in theMiddle East, a major oil producing region. An unstable supply curve coupled with an inelastic demand curve would lead to wide and frequent fluctuations in price.
技巧4-记住内容
当学习包含大量内容的概念(如弹性、规模经济、进入壁垒)时,可以遵循DDEE原则来确保答案的完整性。
Definitions
Diagrams
Explanation
Examples
它更容易记住概念,因为你已经在章节中学习过了。
比方说遇到“Differentiate between internal and external economies of scale (10m)”这样的问题,
根据DDEE原则就能立马想出essay结构:
Definition: Internal EOS are reaped due to growth of the firm while external EOS are independent of firm size and are attributed to growth of the industry.
Diagram: Internal EOS is seen diagrammatically as a movement downwards along the long run average cost curve (LRAC) while external EOS manifests as a downward shift of the entire LRAC.
Explanation / Examples: Sources of internal EOS include technical, marketing, financial or managerial economies. On the other hand, external EOS takes the form of economies of information, concentration or disintegration.
