嗯..
問題出左係依度:
>中,英,數,phy,chem,bio,hist,chist.econ,pth,geog,rsc
>總分1600(英佔300,數佔200,中佔200)
中英數既weight比其他重,所以total唔係12科而係16科

>>總分(所有分數的總和)
>>除以
>>你的科目數目(級級不同)
>>計Grade的不用"理"
>
>如果依你的方法計算的話
>我們form3總共12科
>中,英,數,phy,chem,bio,hist,chist.econ,pth,geog,rsc
>總分1600(英佔300,數佔200,中佔200)

>假設你一共取得1300分(1300/1600)
>再如你所講除科目總數
>1300/12=108.3333333
>平均分便過100了,不合理

>再除16(1600/100)
>1300/(1600/100)=81.25
