Welcome
On, December 13 2008 ,3 students called manipulator, Waffle and sgstudents decided to create a Social Studies website, a resource that would benefit hundered and thousands of singapore's O level / IP cohort batch.
We were tired of always hearing students lamenting about an infamous subject called social studies, some even using the name as a "swear" word.
Hence we decided to take action and to once and for all change this mindset about the subject and get everybody back on track
This subject called Social Studies wasn't created to fail people or to pull down their grades. It was created so that singapore's various races could live in harmony.
