It seems like you may be referring to a study or revision ratio often known as 20:4, which might imply studying for 20 minutes and then taking a 4-minute break. However, without more context, it's difficult to provide specific advice or information.
If you are indeed talking about a study technique or schedule for university exam preparation, it's based on the Pomodoro Technique, which promotes short, focused bursts of work followed by a short break. The traditional Pomodoro Technique uses a 25:5 ratio, where you work for 25 minutes and break for 5 minutes.
To use this technique effectively, you should:
- Pick a subject or topic you need to study.
- Set a timer for your study period (20 minutes, in this case).
- Study with focus and intent during that period, avoiding all distractions.
- When the timer rings after 20 minutes, stop studying and set the timer for a 4-minute break.
- During the break, truly relax. Get up from your study area, walk around, do some stretches, or get a glass of water.
- After the break, reset the timer and go again.
This method helps maintain high levels of concentration while preventing burnout. After four cycles, it's often recommended to take a longer break, around 15-30 minutes.
If you're referring to something different with "20:4," please provide further information so I can appropriately assist you.
