Study in focused blocks
Working in timed blocks with planned breaks makes it easier to start, keeps your attention on one task and stops long sessions turning into scrolling. The classic method, developed in the late 1980s, uses 25 minutes of focus, a 5-minute break, and a longer break after four sessions.
How to use it
- Choose a preset or set your focus time, short break and long break.
- Write down the one task for this session, then press start.
- When the chime sounds, stop and take the break, even if you are in the middle of something.
- After the set number of sessions, take the long break.
Which length to choose
| Preset | Good for |
|---|---|
| 15/3 | Getting started on a task you are avoiding |
| 25/5 | Most studying, reading and revision |
| 45/15 or 50/10 | Writing, problem sets and coding |
| 90/20 | Deep work on a single hard problem |
Make the breaks count
Stand up, drink water, look into the distance and leave your phone alone. A real break helps the next session more than a social media check. Revising for a practical exam? Try the OSCE timer.
Questions and answers
Is 25 minutes the best study length?
It is a good default. Many people move to 45 or 50 minutes once focusing becomes easier.
What should I do in the break?
Move, rest your eyes and get water. Avoid starting anything that is hard to stop.
Can the timer run in a background tab?
Yes. The chimes are scheduled on your device’s audio clock, so they play on time while you work in another tab.
