The 25-minute revision habit
Students often think revision only counts when it feels intense. In reality, the most effective revision habit is one that returns to the same topic before your memory fully fades.

Shorter sessions lower resistance
A 25-minute block is psychologically easier to begin. That matters because the best study plan is the one you can start even on a tired day.
Once a short block becomes normal, it compounds faster than irregular marathon sessions.
Revision works best when it is active
Spend those 25 minutes recalling formulas, explaining a chapter out loud, or answering five sharp questions from memory.
Passive rereading feels productive but usually leaves you with the illusion of understanding instead of proof.
Tie it to a fixed moment
The habit sticks when it is attached to something already stable, like the first 25 minutes after dinner or immediately after school.
Consistency of timing matters more than searching for the perfect mood.
