Liberal Studies is now a mandatory subject in local schools starting from Form 4. It covers "issues relevant to the human condition in a wide range of contexts". And five months into the school year, students and teachers say they still feel overwhelmed by its scope. As producer Vince Lung reports, without specific guidelines or past experience to rely on, teachers are left on their own to decide what to teach, what to exclude, and what to make of the "Liberal" in Liberal Studies.
