MOE now cites screen use displacing sleep as a wellbeing risk and even moved school device curfews earlier. Why the late night grind backfires, and the exam week schedule that works.

When a ministry adjusts a clock, pay attention: from January 2026, MOE's enhanced screen measures moved the default Device Management Application sleep hours on school laptops from 11pm to 10.30pm, alongside the stated rationale that screen use displaces sleep, physical activity and social interactions and is linked to poorer wellbeing. The national Grow Well SG strategy carries a Sleep Well pillar for the same reason: healthy sleep routines improve concentration, mood and physical development.
Fixed wake time seven days a week, revision front loaded into daylight, the last hour before bed screen free and content light, review rather than new material, and the night before a paper protected absolutely, because the season's dates are known months ahead and a schedule built backwards from them never needs the 2am shift at all.
The 2am study session survives because it photographs well in the family mythology, the child sacrificing sleep looks like effort, and I want to say the uncomfortable thing three years of tutoring has shown me: the midnight grinders are usually my weakest performers in the exam hall, not because they work less, but because they work at the wrong hours and sit papers half present. The rested student who stopped at 10.30 keeps beating them, quietly, every season.
Parents hold more of this than they think, because sleep is a household setting, not a student choice: the home that eats dinner at a fixed time and dims by 10pm produces the schedule automatically. So when MOE moved its device curfew half an hour earlier, it handed every parent a sentence I suggest using word for word: even the school laptop sleeps at 10.30 now. Let the child match the laptop, and watch what a fully awake brain does to the same number of study hours.
Some teenagers do lean late, and the honest test is the morning after: a night owl schedule that still delivers a full night's sleep and an alert 8am is a preference, while one that delivers five hours and a groggy paper is a cost, and the exam timetable does not negotiate with chronotypes.
It patches alertness, not consolidation: a short afternoon nap helps the day run, but it does not replace the overnight work of filing what was studied, so naps belong in the plan as a supplement, never as the plan.
Weeks before the papers, because sleep rhythms shift slowly: the child who fixes their wake time at the start of the term walks into exam week already calibrated, and the stress signs worth watching often ease with the schedule itself.
