Manage the drop, not the total
Exam preparation is a months-long project, sometimes a years-long one. Under those conditions the thing worth optimising is not your best day but your worst one. Fourteen hours followed by two days of collapse loses to nine hours repeated daily.
This is where the technique earns its place: it forces breaks. Stopping voluntarily while absorbed is hard, but not stopping is what empties your afternoon. The five minutes you take every half hour is what you pay to keep the second half of the day.
Match subjects to the hour
An hour is not an hour. What follows is one workable layout for a full-time student; adjust it to your own rhythm rather than copying it.
Morning - material that needs understanding
The first two or three hours after you wake are usually when working memory is at its best. Put new concepts and hard problems here, running the standard four sessions and then a long break.
Spending this window on rote memorisation or tidying notes is using your most expensive resource on your cheapest work.
Early afternoon - keep your hands moving
The hour or two after lunch is difficult for almost everyone. Open a dense textbook here and you will read the same paragraph three times. Schedule practice problems, error logs and vocabulary instead, and shorten the sessions.
If you are genuinely fighting sleep, a fifteen to twenty minute nap will buy back the next three hours. Set a timer; past thirty minutes you wake up heavier than you started.
Late afternoon - work in exam-sized blocks
While you still have stamina, do full problem sets or mock papers in one piece, timed to match the real exam rather than to 25 minutes. What the exam demands is the ability to hold a continuous stretch, and that has to be trained directly.
Evening - retrieval, not new ground
Use the last block to recall the day rather than extend it. Close the book and write what you remember on a blank page. Two or three sessions is plenty, and retrieval beats rereading for retention.
Count sessions, not hours
'Studied ten hours today' does not tell you what happened. Daydreaming, tidying the desk and checking a phone are all inside that number. Completed sessions squeeze most of that out.
Set a daily target - sixteen sessions, say - and note how many went to each subject. After a week the neglected subject is visible as a number rather than a vague feeling. Hour logs bend to your mood; session counts mostly do not.
Pomodig shows your completed focus sessions on screen, so at the end of the day you copy one number into your planner.
Rules for the days that collapse
Some days will go wrong. How you handle them decides the following week.
- When a day is clearly lost, do not rebuild the plan. Do one session. The gap between zero and one is larger than the gap between one and ten.
- Do not try to make up several days at once. It usually costs you two more.
- Fix sleep first. Hours borrowed from the night are repaid out of the next day's concentration.
- Review weekly. Daily judgement is emotional and monthly is too late to correct anything.
