If a student does not consider energy level while planning, what problem may occur?

Correct answer: Difficult tasks may be placed at the wrong time

Energy and alertness often vary across the day because of sleep, meals, workload, and individual rhythms. If the most demanding tasks are placed during a low-energy period, concentration and performance may suffer, increasing delay. Planning difficult work during a person’s more alert periods can help, although it should remain flexible. Thus A identifies the likely problem.
