所以你見我用的字眼是 科排名飄上飄落，而不是分數飄上飄落...
亦即高分容易高grade 難

你試吓搵搵 5 的 cut off 可能年年都好穩定。拉 curve 同水平參照是不同的。
你如果搵到幾年Econ 5，5*，5** 的 cut off 可能你的飄忽假設成立。
I searched in internet and found this site, I didn't fact checked their reputation, just use it as an example.

2013- 2020 cut off ranges (Sample size pretty small less than 200.)
Maths. Chem. Bio. Phy. Econ
5**. 89-94%. 84-92%.76-85%.85-90%. 90-93%
5*.81-87%. 79-87%.69-87%.78-83%.83-89%
5.74-82%70-80%.63-72%.65-78%. 78-83%
5** spread 3-9%, lowest Econ, highest Biology
5*. spread 6-18%. lowest Econ, highest Biology
5.spread 5-13%lowest Econ, highest Physics
If we use highest spread -> more fluctuations 較飄忽，then Biology and Physics more unpredictable.
If we use lowest spread -> less fluctuations,冇咁飄忽，then among this subjects Econ more predictable.
Am I correct?
Please enlighten me if I missed some points.
**********
Also lower cut off score doesn't mean it's easier, because different subjects may have different formats for assessment and the marking schemes not the same.
If I take Econ as my choice, 90% is the min for 5**, that's my target. For Biology is 78% min.
