    Martin,

    I believe you know what is copyright. Please show some respect to the person who has worked out the solution and avoid posting it as if it is your own piece of work.

    As you mention in your blog that your son took PSLE 2009, your readers will appreciate that you could help to post questions and solutions not discussed in other forums, eg. Circles, Volume, Area and Perimetr, Algebra.

    Looking forward to your effort. Your blog will be flooded with genuine readers and fans.

    Martin,

    If you are just compiling I believe you have obtained the owner's prior permission before you copy and post them up.

    But I wonder why you have to waste so much time to copy when you could have just provided the URLs for your readers.

    When you copy, I still believe that you should have the courtesy at least to state the original source / owner.
