Frequently asked questions
How many days does the tool count?
The number of calendar days between today and the exam date, measured from midnight to midnight in your local time, with a minimum of 1. If the exam date is left blank, it assumes 14 days. An exam today or in the past also counts as 1 day, so check the date.
How is the revision period chosen?
It reserves 20% of the days, rounded to the nearest whole day and never fewer than 1. Revision days are excluded from active study hours. For 14 days that is 3 revision days and 11 study days. This is a fixed rule in the tool, not something derived from your subjects.
What do the hard, medium and easy percentages do?
Each percentage is applied to the active study hours (study days × hours per day). With 33.0 active hours and weights of 30, 45 and 25, hard topics get 9.9 hours, medium 14.8 and easy 8.3. The numbers are not forced to total 100.
What if my weights do not add up to 100%?
The hours are allocated as typed, so they may add up to less or more than the active total. The “Weights total” row tells you the sum and how many hours are actually allocated. With 50, 30 and 10 (total 90%), only 14.4 of 16.0 active hours are allocated.
Why does “hours per topic” ignore difficulty?
It is just active study hours divided equally by the number of topics. The hard, medium and easy rows are separate pools; the tool does not know how many of your topics belong to each group, so it cannot split them per topic.
Does it make a day-by-day timetable?
No. It gives totals and pools of hours. You decide which topic goes on which day.
What happens with blank or tiny inputs?
A value of 0 for hours per day, which is also what a cleared box becomes, counts as 3, and anything between 0 and 0.5 is raised to 0.5. A number of topics of 0 counts as 5.
Study schedule calculator — hours by topic difficulty before an exam
What the calculator allocates
From your exam date and daily study hours, the tool counts the days left, multiplies by the hours you can study to get a total, and then holds back the final 20% of days for revision. The remaining active hours are divided into hard, medium and easy pools using the percentages you set, and also split equally across your topics for a per-topic average. It does not choose topics or build a calendar; it tells you how big each pool of time is.
Worked examples
With no exam date, the tool assumes 14 days. At 3 hours a day and the default 30/45/25 split, that is 42.0 total hours, 33.0 active hours over 11 days, 9.9 hours for hard topics, 14.8 for medium, 8.3 for easy, 6.6 per topic with 5 topics, and 3 revision days. For an exam 30 days away at 4 hours a day and 6 topics, the totals are 120.0 hours, 96.0 active hours over 24 days, 28.8, 43.2 and 24.0 hours for hard, medium and easy topics, 16.0 per topic and 6 revision days.
The revision rule at different horizons
Because revision is 20% rounded to the nearest whole day, with a minimum of one, the real share moves around. A five-day plan keeps one day (20%), a seven-day plan also keeps one (about 14%), and a 14-day plan keeps three (about 21%). The table shows the totals at 3 hours a day.
| Days until exam | Total hours | Study days | Active hours | Revision days |
|---|---|---|---|---|
| 5 | 15.0 | 4 | 12.0 | 1 |
| 7 | 21.0 | 6 | 18.0 | 1 |
| 10 | 30.0 | 8 | 24.0 | 2 |
| 14 | 42.0 | 11 | 33.0 | 3 |
| 21 | 63.0 | 17 | 51.0 | 4 |
| 30 | 90.0 | 24 | 72.0 | 6 |
Short timelines and mismatched weights
With only one day left, the tool keeps that day as revision, so active study hours are 0.0 and every topic pool reads zero. If your three percentages total 90, as in a 10-day plan at 2 hours a day with weights of 50, 30 and 10, the pools come to 8.0, 4.8 and 1.6 hours, and the Weights total row warns that only 14.4 of the 16.0 active hours are assigned. Adjust the weights until the row reads 100%, or accept that some time stays unallocated.
