How to use this calculator
Enter total topics, topics already reviewed, difficult topics, and average minutes per topic. The calculator assumes a 10-day revision window for quick exam planning.
Difficult topics receive extra review weight because they usually require more practice and repetition.
What the result means
The result shows total revision hours and daily topic load. A lower load means you are close to ready. A high load means difficult topics should be prioritized immediately.
Revision hours = Remaining topics × Minutes per topic + Difficult topics × Minutes per topic × 50%
The default 10-day window is useful for final review planning. Adjust mentally if your actual exam window is shorter or longer.
