A-Level经济考试四大重要得分点

Tip 1-事件的影响
  纵观整个经济大纲,经常会要求学生评估事件对某一事物的影响。

  在解决这样的问题的时候,可以参考这些分析范围:


  Tip 2-集中精力于经济分析
  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。

  有一个70/30的原则。举两个例子:


  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。
  Tip 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。
  举个例子
  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.


  Tip 4-记住内容
  学习内容很多的概念时(比如说弹性概念、规模经济、进入壁垒),可以参照一个DDEE的原则保证答案的完整性。
  Definitions
  Diagrams
  Explanation
  Examples
  这样学习概念更方便记忆,因为之前大家的知识是分段的。
  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.
  嗯,就是这样了,考前值得一看!
