A-Level經濟考試既是考核學科知識，也是考察學生的考試能力，學通國際教育今天給大家介紹的就是exam-smart tips，幫助大家考試拿高分！
縱觀整個經濟大綱，經常會要求學生評估事件對某一事物的影響。
在解決這樣的問題的時候，可以參考這些分析范圍：
寫經濟essay的時候，時間總是緊張的。那么知道內容比例的劃分就尤為重要，解釋content占多少，簡潔的explanation占多少。
有一個70/30的原則。舉兩個例子：
Theory of CA包含很有價值的經濟分析，學生應該解釋它的假想條件，比較機會成本比率，得出貿易可以獲得什么。
Material SOL要求具體的經濟分析，包括實際GCP與名義上的GDP數字、收入分配、按PPP計算的GDP。
非常有用，但也經常被忽視的一點。意思就是看一下自己的topic sentences，是否用較直接的方式回答了問題。有時候，我們有些段落可能是用來介紹背景信息但卻沒有直接回答問題。
舉個例子
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.
學習內容很多的概念時（比如說彈性概念、規模經濟、進入壁壘），可以參照一個DDEE的原則保證答案的完整性。
Definitions
Diagrams
Explanation
Examples
這樣學習概念更方便記憶，因為之前大家的知識是分段的。
比方說遇到“Differentiate between internal and external economies of scale (10m)”這樣的問題，根據DDEE原則就能立馬想出essay結構：
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.
