Pupils of Tonj South County Primary School in Warrap State on Monday resumed their normal classes.
The School head teacher William Majok said pupils started happily after a two-week holiday, Don Bosco Radio reported.
He called on those pupils who did not turn up, to hurry and resume because their colleagues are getting revisions, corrections of the past exams and new lessons.
Mr Majok urged all teachers to commit to hard work for pupils to emulate them to achieve the development of South Sudan.
The head teacher advised parents and guardians to allow their children to go to school to become future leaders.
