teacher teacher, im sorry i didn't finish my homework because i dont know how to finish it. haha-----> lepas tu kena sumpah seranah, terima kasih. last week cikgu ada bagi exercise chemistry, but aku tk buat. alasan bodoh (err tktau nk tulis jawapan mcm mana). betul! soalan dia mcm pelik sikit. so nk tulis jawapan tapi ada dua tempat kosong. haha, so let it be empty then i'll ask my friend in the class tomorrow. teehee :D
