How to use the daily problem count calculator
If you want to finish a practice workbook before a test, this page works out how many problems a day that takes. Enter the total number of problems, the problems you have already finished, the days left until your target date, your study days per week, the average time per problem and an expected error rate. The tool returns a daily problem count and the study time that count requires. Unlike a lecture-based course planner, it works in problems and minutes rather than video lessons.
Problems remaining is the total minus the problems already finished. The expected error rate adds the share you plan to redo, giving an effective problem count. Usable study days are the days left multiplied by your study days per week divided by seven, rounded down. The daily problem count is the effective count divided by usable study days, rounded up, and daily study time is that count multiplied by your average time per problem.
The error rate is an assumption you supply from your own past results; this page does not predict how many problems you will miss. It also does not model differences in unit difficulty, the longer time free-response items take, or the time spent grading and writing up mistakes. It does not schedule review dates.
Frequently asked questions
Enter 0 as the expected error rate and the tool divides only the problems left, with no redo workload added.
Rounding down leaves problems unfinished on the last day even if you hit the daily target, so the count is rounded up to fit the deadline.
Enter 2 study days per week and the tool counts only two sevenths of the days left as usable study days.
