1. negeri mana nih??

2. btul ke semua soalan nie??????

3. Ramalan spm ke nie ?

4. betol ke x ni???? perlu di disiasat ni

5. ini macam soalan trial selangor..
takkan sebiji jadi soalan spm sebenar kott -,-'

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

7. i think just state paper...

8. just ramalan.....

9. soalan trial negeri or ramalan spm?

10. mcm trial negeri perak je..

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