General note on item deletion
It is normal for the HKEAA to delete a small number of items from its multiple-choice question papers if they prove unsatisfactory. In practice, there are a number of reasons why this is considered necessary. By far the most common reason for deleting an item is that the item fails to discriminate between weak and able candidates — in other words, the majority of the candidates involved had to rely on guesswork in answering that question. If such an item is retained, the measurement process is rendered less effective. Where items have been deleted in the live papers, they are still included in this series of publications. They are indicated as deleted items. Such items may be discussed in the corresponding examination reports.

在香港的中學公開試中,間中有一些多項選擇題(multiple choices),會在考試後被考試局刪除。換句話說,那些題目的分數,不會計算在總分之中。

某一題被刪除,其中一個可能的原因是,該題每個答案的選擇人數差不多,都是大概 25%。那就即是話,大部分人也是隨意估計的。那樣,該題就失去了考試的意義,因為它不能再用來,判別考生學問的高低。

對於任何一題,只要在指定時間內想不到,就應該立刻暫時放棄。你應先隨機填一個答案,待完成了其他題目,還有時間剩餘的話,才回來再想。除了我以前講的理由外,現在還多了一個考慮:

某一題所需的思考時間過長,並不一定是因為你的才能不及。那亦可能是該題過深,根本絕大部分其他考生也不懂做。如果你堅持要完成,即使最終得到正確答案,也會得不償失。一來,你已經用了過多的時間,導致自己來不及,妥善完成其他題目。二來,該題最終可能被取消。

留意,即使決定了暫時放棄某一題,你也一定要先隨機填一個答案,才去做下一題。在多項選擇題的答題紙上,留下空格,是極之危險的事情,因為那可能會導致你,往後題目的答案「轉移」,全部填錯位置。
