For the average JC H2 maths student, doing tutorials alone is not enough to pass mid year or promo exams. This is because many JCs set the exams at a much higher standard than tutorials. In some JCs, about half of the cohort can fail JC 1 promo.
To do well, other than doing tutorials, students need to practise intermediate or advanced questions. If they are unable to do intermediate questions, they should seek help early from a good tutor.
If students fail or barely pass their mid year or promo, don’t wait until JC 2 to brush up. Otherwise, they have to struggle to catch up and learn new challenging topics in year 2.
