或者咁講:you need to know all the things written in the syllabus, but that's not all you have to know for the exam.
好似2015有條叫你suggest two practical methods to confirm the feeding relationships among various organisms in an ecosystem.
Syllabus冇提過,書都(好似)冇講,但佢出咗,turn out超過一半人攞零分
雖然答案某程度上係common sense,but my point is,唔好睇到嗰syllabus係一個好死嘅考試範圍
