Kertas 2 Matematik SPM ini mengandungi 15 soalan yang Wajib dijawab dan membawa markah sebanyak 100%. Kertas 2 ini juga dikenali sebagai LUBUK EMAS untuk mengorek markah semaksimum yang mungkin dalam Matematik SPM.Ini kerana Soalan-soalan yang ditanya adalah lebih mudah sedikit daripada kertas 1.Walaupun Kertas 2 merupakan soalan berbentuk subjektif tetapi percayalah Ianya adalah lebih mudah dari kertas 1.Jika anda selalu gagal dalam peperiksaan apa kata tumpukan pada kertas 2 ini sebagai persediaan terakhir sebelum memasuki dewan peperiksaan sebenar nanti..Disinilah perbezaan gred akan berlaku sama ada anda akan dapat A,B,C atau D..anda masih boleh meningkat dengan mendadak dari D ke B dari C ke A jika kena dengan caranya. Daripada statistik Soalan Peperiksaan Sebenar 2005-2011 dan statistic soalan Percubaan negeri 2012,maka berikut merupakan tajuk-tajuk yang perlu CALON SPM 2012 beri tumpuan bagi tahun 2012 dalam KERTAS 2.
