PETALING JAYA: All five million students are in school today, the first time that everyone is back since the country had to grapple with the third wave of Covid-19 cases. While schools started welcoming back students as early as March 1 this year, only preschoolers and pupils in primary Years One and Two, followed by those in Year Three to Six a week later, were allowed into their classrooms then under a staggered return. All secondary school students have resumed schooling today after five months, starting with those in Johor, Kedah, Kelantan and Terengganu yesterday. The reason that secondary school students were the last to physically return to school was to make way for the SPM and STPM 2020 examinations, which were postponed to early this year.
