The maths behind it

This tool uses Hours needed = topics × hours per topic. Required daily pace = hours needed ÷ days available. Every intermediate value is shown on screen, so the result can be checked by hand.

Plan in 45-minute blocks rather than hours — a "three hour session" is usually ninety minutes of work and ninety of drifting. Spacing and retrieval practice do far more for recall than a longer first pass.
