-        <p>
-          While it is true that Timetable Planner is able to export the schedule to the calendar, it is not flexible as
-          UST Schedule. Users are not allowed to add duplicate courses (except for using the "import to current
-          timetable" feature, but still, it is not flexible). Users are not allowed to add individual lectures,
-          tutorials or labs without adding the full course.

-        <p>
-          Additionally, UST Schedule is able to show the location of the venue via Path Advisor.
