Yea,just finish my physics paper and reach home.
Today my brain was full of physics,now I gonna turn it to CHEMISTRY status.

Hmmm,about the paper...
I think it's okay,but there are many traps inside and unluckily I have droped inside some of them.T.T
Paper 2 got some don't know but still I didn't let it blank,I simply write some answer to fill it,hope I can write it right^^At section B there,aarrhh,about the Archimedes's principle,lack of points there,hard to blow water,haiz.Give up there and losses marks.
For paper3,I don't know I can score or not.
Hope can get good result.
