negeri mana nih??

ReplyDeletetadi ?

ReplyDeletebtul ke semua soalan nie??????

ReplyDeleteRamalan spm ke nie ?

ReplyDeletebetol ke x ni???? perlu di disiasat ni

ReplyDeleteini macam soalan trial selangor..

ReplyDeletetakkan sebiji jadi soalan spm sebenar kott -,-'

ini benar for spm 2012?atau ambil drpd state paper? pls reply

ReplyDeletei think just state paper...

ReplyDeletejust ramalan.....

ReplyDeleteYa..

ReplyDeletesoalan trial negeri or ramalan spm?

ReplyDeletemcm trial negeri perak je..

ReplyDeletejust take note jelah...baca semua...kalau tak tepat pun at least semua dah ada back up..
