Pointer?

Met my sister at our kampung. I asked her about her pointer.
Baru nak action cakap my results is 3.75 above.. How unfortunately,

she answered, "I got 4flat." What in the world?

But yes, theres no doubt she is smart.

Haahhh, Im dying to get that in my exams! :(
But whatever, congratulations sis!
I just proud of you! ;)
