I have just gotten a copy of the SPM 2009 Add Maths Paper 2 from my student.
I have done a discussion on Section A with workings via an online tuition school. You can view it here at www.cramschool.com.my. Just click on the demo for Add Maths and you’ll get the lesson
You can also click on the Physics demo and you’ll get a lesson that I did on Form 4 Physics Chapter 4 Heat.
