Study Time Planner
Tell us your total available study hours, how many days until your exam, and rate each subject's difficulty — we'll split your hours accordingly.
*Estimates only. Adjust based on your own pace, energy levels, and how your exam is weighted.

Weighted Grade Calculator📚 Smarter Study Allocation
The logic behind distributing limited study time across competing subjects.
How it Works
Rate each subject's difficulty and importance from 1 to 10. The planner treats these ratings as weights and proportionally divides your total available hours so tougher, higher-stakes subjects get more time.
The Formula
Subject Hours = Total Hours × (Subject Difficulty ÷ Sum of All Difficulty Scores). Daily Average = Total Hours ÷ Days Until Exam.
Pro Tip
Break each subject's allocated hours into 25-45 minute focused blocks with short breaks. Studying your hardest subject first, while your mind is freshest, often produces better results than saving it for last.
Frequently Asked Questions
How does the planner decide how many hours to give each subject? +
You assign each subject a difficulty/importance score from 1 to 10. The planner adds up all the scores, then gives each subject a share of your total study hours proportional to its score relative to the total. A subject scored 8 gets roughly twice the hours of a subject scored 4.
What counts as a good difficulty score for a subject? +
Base it on how hard the material is for you personally combined with how much it counts toward your grade or exam. A subject you're struggling with that also carries heavy exam weight deserves a high score (8-10); a subject you already know well with a small quiz deserves a low score (2-3).
How many total study hours should I plan for before an exam? +
This varies widely by exam type and course load, but many students find 1-2 hours per day per subject in the two weeks before a major exam to be sustainable. Cramming everything into the final 48 hours tends to produce worse retention than spreading study sessions out.
Does the planner account for spaced repetition or breaks? +
No, this tool only allocates total hours across subjects proportional to difficulty. Within each subject's allotted time, using techniques like the Pomodoro method or spaced repetition for memorization-heavy material will make your study time more effective.
What if I have more than four subjects to study? +
This calculator supports up to four subjects at once. If you have more, group closely related subjects together, or run the calculator twice, splitting your total hours between two batches of subjects.
