In which situation will improved scheduling not increase productivity?

Correct answer: When scheduled time is spent on distracting activities

A schedule can allocate hours, but productivity also depends on how those hours are used. If the student spends the planned study period on messages, entertainment or other distractions, the schedule produces little meaningful work. Clear goals, proper priorities and review can support productivity, but they cannot compensate for persistent loss of focus. Therefore, B is the situation in which better scheduling alone will not help.
