No, General Paper does not count.
In the UK and other countries it's not uncommon to see people take 5 or more subjects (out of Maths, Further Maths, Physics, Chemistry, Biology, and Economics in particular, and sometimes Literature and History). However, they take this in almost 2 years, and it's often the modular kind where you can resit individual, 1/6 part components.
6 subjects is a bit extreme (not necessary, and for a Science degree, Literature and in some cases Economics would just be indulgences). However, if done over ~2 years, that's about 3 per year, not unlike the 3 per year that many of us have gone through - obviously not comparable since 6 exams will be taken at a go for A2/the final stages.
In Malaysia they just want you to do as well as possible at a minimal level to enter good universities (for those who can and want to), hence you're encouraged to take only 3-4 (and classes are only scheduled for that many, since the length of study is barely 1.3+ years, or in some cases, a year).
I disagree, Further Maths is quite useful for a lot of things. For one, it is a requirement for many Mathematics degrees and permutations of these with Statistics, Economics, Finance etc. It is also a new requirement for MORSE/MMORSE (next year on). It is also very useful for admission into and the study of Engineering degrees, and is revelant to admission and the study of Operational Research, Computing or Computer Science/Engineering, Statistics, Computational Finance, Financial Engineering, Quantitative Finance, Economics, Econometrics, Financial Economics, Financial Mathematics, Risk Management etc.
Even students who wouldn't really use it tend to take it - like those planning to do Medicine, Dentistry, Law, Accounting etc.
My son will be doing his A levels in 2012. As he has no interests in pursuing science related degree courses, and he did not do too well for spm (struggle with Bs and Cs), the subjects he will most likely be taking for A levels wld be:
1. Maths
2. Economics
3. English Literature
I read from the LSE website that law A levels is not really an advantage. Still, we are weighing the option betwee phylosophy, law and further maths. His strong A subjects for SPM are maths, add mths, english and eng lit.
