Quick summary
Enter how many chapters or topics you have, the hours each takes, and your days until the exam — the calculator works out the total study hours, how many hours per day that requires, and whether it fits the time you actually have free. If the required pace exceeds your available hours, it tells you by how much you're short so you can start earlier or add sessions. Spacing study over more days beats cramming.

Frequently asked questions
How many hours a day should I study for an exam?
It's the total material divided by the days you have. Twelve topics at 2 hours each is 24 hours; over 14 days that's under 2 hours a day, but over 3 days it's 8 — likely unrealistic. This calculator computes the required daily hours and flags when it exceeds your free time.
Is it better to cram or space out studying?
Spacing wins. Decades of research on the 'spacing effect' show that spreading study across more days produces far better retention than the same hours crammed together. Starting earlier lowers the daily load and improves recall — the calculator makes the earlier-is-easier tradeoff concrete.
How do I make a study schedule?
List your topics, estimate the hours each needs, count your days until the exam, and be honest about free hours per day. Divide the workload across the days, front-loading harder material and leaving the final days for review and practice tests rather than first-time learning.
What if I don't have enough time?
If the required pace exceeds your available hours, prioritize: focus on the highest-weight topics and your weakest areas, use active recall and practice questions over re-reading, and consider which material you can afford to skim. The calculator shows exactly how many hours short you are so you can triage realistically.
