2012-2017 HKDSE Math 歷屆數學不同級別(Grade)所需分數 cut off 及其分析

本文目的:
坊間 cut-off 出處係邊?準嗎?啲 cut-off 原貎(原始數據)係點?真實 cut-off 係幾多?啲 cut-off 數據,有否反映出其他資訊(如考卷深淺變化)? 本文希望能為此提供答案。(如有問題請留言
(一) 坊間 Cut-off 來源:某大討論區 網上所有 Cutoff 資料,其實全出自某學生討論區,佢地每年都收集分數 (覆卷考生無私交出 check 卷結果),再整理 得出大約既 Grading 分數*,使莘莘學子得益。
(*係大約咋,下文會講點解係大約,同應該點用呢啲數據)

(點解考試局唔公開呢啲資料呢?好多外國公開試都有咁做。)
(唔唔,應該係,除非唔係。)

原文見 Fact of the Day: Hunting is Safer Than Bowling?

According to the National Shooting Sports Foundation, hunting with firearms is one of the safest recreational activities in America (here's the press release and here's the fact sheet with sources provided). 
Based on the percentage of injuries per 100 participants, hunting with firearms (0.05%) is slightly safer than bowling (0.06%) or jogging (0.08%) and slightly less safe than billiards (0.02%), see chart above.  
The organization also points out that compared to hunting a person is: 11 times more likely to be injured playing volleyball 19 times more likely to be injured snowboarding 25 times more likely to be injured cheerleading or bicycle riding 34 times more likely to be injured playing soccer or skateboarding 105 more times likely to be injured playing tackle football.
Not surprisingly, the least safe sport is football (tackle) by far, followed by basketball, skateboarding, soccer, wrestling and bicycle riding (see chart below).
