    1. Yes. In the chapter '' International trade - quota, tariff, subsidies,etc

    2.

    Change in demand:

    This is caused by a change in any other factors (income, taste, etc.) except its own price.

    This is represented by a shift of the entire demand curve.

    Change in Quantity demanded:

    This is caused by a change in its own price, holding all other factors constant.

    This is represented by a movement along the same demand curve.

    3. ''Demand and Supply' will be about 20% of a paper.

    係啊 因為demand supply係會考課程的大topic 唔識你好難會考得好

    要 會連埋深1點的topic問 (好似international trade 啊trade restirction 咁)

    所以你最好打返好個底 咁樣你form 5 時會易明啲

    change in demand 係 非價格因素 的effect

    eg: 而家新聞話飲奶好 我地買多d奶 奶的demand上升就係change in demand

    change in quantity demand 係價格因素 的effect 都等同"LAW OF DEMAND"

    eg: 而家奶平了 我地買奶買多左 咁樣係change in quantity demand

    而個graph方面 change in demand 係會有2條demand curve的方向改變

    change in quantity demand就只有1條curve 而且係線上2點的改變

    我其實以前econ 都好差 我建議你補習的話可以考慮kevin ko

    佢會幫你清concept

    如果你有econ野問都歡迎pm我:)
