ECON objective 係咪即係指老師會集中喺個答案到搵 key point？
即係我答點解 Historical Cost 唔係 Cost，就話咩 no way to get it back =.=?
而家我教到 Price Searching & Monopoly
佢教得太 ...
唔知版友知唔知ECON卷點改? 每條ECON題目(SQ或LQ)都只會由同一組好幾個老師改，所以改卷老師會易D 有共識點去比分，其他科係無呢個安排。
因為AL ECON好重理論分析，並不可以加任何主觀情緒(METHODOLOGY呢課書已好強調呢樣野)，因此ECON要高分只須要好小心THEORY邏輯推論，記住要逐步去EXPLAIN，仲有DEFINITION好值分(例如LAW OF DIMINISHING RETURNS 定義值3分喔)，如果DEFINITION INCOMPLETE會勁失分。
如果答SUNK COST題目，首先要DEFINE SUNK COST、(OPPORTUNITY) COST。
我試下寫下SUNK COST SQ點寫(只有ENG版):
Since sunk cost is the past cost of a past action and it is no longer an available option now, it cannot be recovered. Bygones are bygones. It is irrelevant to decision-making and so sunk cost is not cost at all.
因為COST呢個CONCEPT好抽象，所以最好舉EXAMPLE。當然，如果冇時間就要SKIP EXAMPLE。不過COST呢個CONCEPT本身寫唔係好多野，所以係絕對有時間舉例。
for example, if you have bought a movie ticket of $50 and the resale value of the ticket is $40, there is a fall in value of the ticket of $10. The $10 mentioned is sunk cost. Whether to resell the ticket or not does not depend on the $10 fall in ticket price, but the resale value of the ticket ($40) and the expected benefir of watching the movie.
所以要寫好一條ECON ESSAY係幾難，同埋練好ESSAY係要花好多時間，仲有要睇參考書(例如CHAN&KWOK)點去演繹一個CONCEPT。仲有，PAST PAPER SQ OFFICIAL MARKING係唔可以死背，因為STEVEN CHEUNG寫MARKING好鬼懶，佢會MISS晒LOGICAL DEDUCTION，但係LOGICAL DEDUCTION係佔好多分。改卷老師唔係好似CE咁去TICK POINT，係會睇晒成個推論。
PS: AL ECON係唔可以補KK，因為佢唔識教寫ESSAY方法/冇心教ESSAY。反而QUEENIE WU(前HSSC名師)真係可以TRAIN到學生去寫ESSAY同埋清CONCEPTS一流
