Free 25 minute study timer for focused study sessions. The classic Pomodoro study interval — 25 minutes of active studying followed by a short break.
Active recall is the most effective technique: close your notes after reading a section and write down everything you remember. Then check what you missed. This "retrieval practice" is 2–3x more effective for long-term retention than re-reading or highlighting. Use 25 minutes for 3–4 retrieval practice cycles.
Regular study: 6–8 sessions (2.5–3.3 hours focused work). Exam preparation: 10–12 sessions. Each session on different material prevents fatigue from a single topic. Track completed sessions — the visual record shows real study time (not total time "at the desk").
Move: walk to another room, stretch, get water. Optionally: spend 2 minutes trying to recall what you just studied before looking at notes. This brief recall during the break consolidates memory better than simply resting. Avoid your phone — social media breaks extend into much longer distractions.
For active recall: yes, return to the same material across multiple sessions (spaced repetition). For initial learning of new material: 2 sessions maximum before switching to avoid diminishing returns. For problem-solving (math, coding): 2–4 sessions on the same problem set develops persistence and depth.
Yes, but modify the technique. For textbook reading: set a goal (X pages or X sections), read actively (take brief notes after each paragraph), never just highlight. For light reading: 25 minutes works without modification. The timer creates urgency that reduces the passive drift that often happens during extended reading sessions.
