Before 1978 the span of school years was 12. Now, students study for 13 years in schools. "To release the exam results of G.C.E. O/L , it takes 3 months and students are compelled to stay at homes for another 3 months to commence G.C.E A/L classes". This is a waste of time and as a result "students study in schools until 19 years old which is the legal beginning of adulthood". Therefore, the span of school education can reduced and should reduced.
