So, one of my S1 students thought he might not be able to stay at Poly next semester, because the time change was going to conflict with his soccer time. He went and took a test to be leveled at a different school and he tested at a grade 5 level!
The funny thing? For an S1 student, he isn't especially high. We have 4 classes and he's in the second lowest. At most, he's been studying here at Poly since preschool, though he might have started in kindergarten.
