Study Planner

Split your subjects into daily study sessions

List what you have to revise and when each exam falls. The planner divides every available day into whole sessions and hands them to the subject that needs them most right now. Everything is worked out in this browser and saved on your device.

How the split is decided

Each subject gets a score of 1 for easy, 2 for medium and 3 for hard, divided by the number of days left before its exam. The day is then shared out in proportion to those scores.

A subject leaves the plan on the morning of its exam, so the day before is the last one it can be revised.

How to use it

Start with the subjects. Give each one a name, the date of the exam and how hard you find it, judged by your own experience of the material rather than by how hard the course is meant to be. Difficulty is the only lever that says one subject deserves more of your week than another, so it is worth being honest about it.

Then set the two constraints. Turn off the weekdays you know you will not study, and set a realistic ceiling on minutes per day. The planner only ever schedules whole sessions, so a 120 minute cap with 25 minute sessions gives you four sessions and 20 minutes of slack, not four and a bit.

Reading the schedule

The day-by-day table covers the next two weeks. Each entry names a subject and how many sessions it gets that day, and every entry links straight to the Pomodoro timer so you can run them without setting anything up. The summary above it shows the whole horizon: total sessions, total hours and the average number of sessions a week between now and each exam.

An amber flag appears next to any subject that gets fewer than three sessions in total. That is the planner saying the exam is too close, or the daily cap too low, for the split to mean much. The fix is more days, more minutes, or accepting that this subject will be revised in one block rather than spread out.

What it does not do

There is no notion of topics inside a subject, no tracking of what you finished, and no catch-up debt. Each morning the plan is recomputed from the dates alone, which is why a missed day quietly raises tomorrow instead of leaving a hole in the schedule.

A worked example

Three exams: Statistics in 6 days, marked hard. Biology in 13 days, marked medium. Art history in 24 days, marked easy. Sessions are 25 minutes and the daily cap is 100 minutes, which is four sessions, and every weekday is available.

Day one

The scores are 3 divided by 6 for Statistics, 2 divided by 13 for Biology and 1 divided by 24 for Art history. That gives 0.500, 0.154 and 0.042, so the shares are roughly 72, 22 and 6 percent of the day. Four sessions cannot be cut that finely, so Statistics takes three, Biology takes one and Art history takes none. The distant easy subject is not neglected out of spite; it simply has weeks of room left and Statistics does not.

Day eight, once the Statistics exam is done

Statistics has left the plan. Biology now has 6 days left and scores 2 divided by 6, or 0.333, against 1 divided by 17, or 0.059, for Art history. Biology takes three sessions and Art history takes one, so the subject that was getting nothing a week ago is now in the rotation without you having changed a setting.

After the Biology exam

Art history is the only subject left and takes all four sessions a day until its exam. Over the full 24 days it ends up with a solid block of hours, most of them in the last stretch. If you would rather it started earlier, mark it medium instead of easy and the weight goes up everywhere at once.

Frequently asked questions

How many hours a day should I study?

There is no single right number, and the honest answer depends on what else is in your day. Two to four hours of genuinely focused work is a realistic target for most people alongside classes, and it is more useful than a longer stretch where the last two hours are spent rereading notes. Set the daily cap to something you can hit on an ordinary day rather than your best one. A plan you keep to at 100 minutes beats a plan you abandon at 300.

Is it better to study one subject a day or mix them?

Research on learning generally supports spreading practice over time rather than massing it into one long session, and mixing related material within a session, often called interleaving, tends to help retention of that material compared with doing one type at a time. The effects are clearest for problem types you have to tell apart, and interleaving usually feels harder and slower while you are doing it, which is part of why people avoid it. This planner leans toward the middle: it will give one or two subjects most of a day rather than slicing it into five, because switching has a cost too.

How long before an exam should I start?

For a normal end-of-unit exam, two to three weeks of steady sessions is usually enough to spread the material out. For a large cumulative exam, start six to eight weeks ahead so each topic can come round more than once. The practical test is whether the planner can give the subject more than a handful of sessions. If it cannot, you are inside the window where the plan turns into a single push.

What if I miss a day?

Nothing breaks. The plan is recalculated from today every time you open the page, so a missed day is not carried forward as debt. What happens instead is that every subject now has one fewer day before its exam, its weight rises, and the remaining days get slightly denser on their own. Resist the urge to repay the missed sessions on top of tomorrow. Either accept the tighter plan or raise the daily cap a little across the rest of the week.

Where is my plan saved?

In this browser, in local storage on your device. Nothing is sent anywhere, which also means the plan will not follow you to another browser or another machine, and clearing site data will remove it. If you want a copy on paper, the printable planners in the templates section cover the same ground.
