i thought currently there are already jc with 0 points?
Perfect score, 6A1
6 points - 2 higher mt = 4
4 points - 2 cca = 2
2 - 2 affiliated school = 0
You never heard before meh?
maybe from 0 still can minus some other shit to make it
negative. 
no one got 0 yet lor... pls...
if negative, then that person must be called
'dumbass' instead... cos he/she did something that
no one can even do in the system...
