I think everyone has a need to study Social Studies, even if it means 1 full week of studying, as you cannot really depend on your elective geography/history/literature to pass. If a person only depends on one subject to pass both, it is no different from flipping a coin with tails for both sides.

But of course, elective is not impossible to score. Social studies, as Ms Yong said, is really easy to score, if the person has even bothered to read a little bit of it.
