Evaluate the effectiveness of common time‑management and prioritization strategies used by high school students—such as planners, time blocking, the Eisenhower Matrix, SMART goal-setting, and routines—and how these strategies influence academic performance (grades, task completion) and personal wellbeing (sleep, stress, extracurricular balance). Assess evidence, compare strengths and limitations across student contexts, interpret simple intervention data, and recommend practical, equitable adaptations for diverse Grade 9–12 learners.
