Formula used
This timer estimates a practical focus cycle instead of claiming a clinical measure. It blends your current attention pattern with study demands.

FAQs
1. What does the attention score mean?
It is a planning score from 1 to 100. It combines your focus length, energy, distraction cost, difficulty, and efficiency. Higher values suggest your session design is more likely to feel stable and sustainable.
2. Is this calculator only for exam revision?
No. It fits reading, question practice, mock tests, writing, and review sessions. The labels are built for test prep, but the timing logic works for most study tasks.
3. Why can the recommended focus block be shorter than observed focus?
The calculator reduces raw focus time when difficulty, retention demands, interruptions, or warm-up drag increase. A slightly shorter block often protects accuracy and recall better than forcing a longer session.
4. What counts as a distraction?
Any interruption that breaks concentration counts. Examples include phone checks, messages, social media, room noise, side conversations, or switching tabs without a learning purpose.
5. How should I choose recovery minutes per distraction?
Estimate the average time needed to fully re-enter focus after an interruption. Many learners fall between two and five minutes, but deep problem solving may need longer.
6. What is the fatigue index used for?
The fatigue index highlights how demanding your setup feels. Higher values usually mean harder content, more interruptions, longer warm-up time, or a stronger retention target.
7. Can I use the output as a strict medical measure?
No. This is a study-planning tool, not a medical or psychological assessment. Use it for pacing and structure, then adjust based on your real performance and comfort.
8. When should I update my inputs?
Update them whenever your energy, subject difficulty, or distraction level changes. Recalculating before each major study block keeps the timer closer to current conditions.
