Important things to consider in this data analysis

  • Only courses with examinations were appeared on the website
  • The result only shows the diversity of type of courses student enrolled into, but not the majority of students enrolled into

Sidenote when trying to collect new datas

  • Previous semester examinations data will disappear after some time
  • Current semester data only appear after the examination timetable has been announced for the majority of students (typically around the end of October for semester 1)
