Estimate study hours to raise a grade.
The hours a grade improvement costs scale with the size of the gap, and the honest input is your own historical rate: how many focused hours it has previously taken you to add one percentage point in this subject. Multiply the gap by that rate for the total, then divide by the weeks left to see the weekly commitment the plan actually implies. The rate is not constant — gains from 50% to 60% come far faster than 85% to 95% — so raise the hours-per-point figure when you are already near the top of the scale.
Study hours for a target grade
Total hours = (target % - current %) x hours per point; weekly hours = total / weeks left
Look back at a past module: divide the focused hours you logged by the improvement you actually achieved. Two to four hours per point is typical for mid-range grades; budget six or more above 85%.
No. Beyond roughly two focused hours per session, retention drops sharply, and re-reading is far weaker than retrieval practice. The hours figure here assumes effective study methods, not time spent with the book open.
Two levers work: extend the timeline, which divides the same total across more weeks, or lower the target. The sustainability band flags when a plan has crossed from demanding into self-defeating.
