Fifteen minutes a day beats three hours on Sunday

Most students know the feeling: a big study session planned for the weekend, which turns into an afternoon of rereading notes and remembering very little of it by Monday. A short session every day usually works better — not because the minutes are magic, but because coming back to an idea again and again is how it moves into long-term memory.

A routine that fits in 15 minutes

1. Two minutes: look back. What did you learn yesterday? Say it in one sentence, without looking.
2. Eight minutes: one new idea. One concept, one example, one picture of it in your head. Not a whole chapter.
3. Four minutes: test yourself. A few questions on today’s idea, and one on yesterday’s. Check why each answer is right, not only whether it is.
4. One minute: write down what confused you, so tomorrow starts there.

Make it easy to start

• Same time every day — after school or after dinner works for many students.
• Pick the goal before you sit down. “Understand refraction”, not “study physics”.
• Keep the streak, not the score. Showing up daily matters more than a perfect day.

On busy days, do five minutes instead of skipping. A short session keeps the habit alive, and the habit is what carries you through the year.
