How to use the daily lectures calculator
Most online courses stall around the halfway mark, and the usual reason is that no daily quota was ever set. Enter the total number of lectures, how many you have already watched, the days left until your finish date and how many days a week you actually study, and this calculator tells you how many lectures a day keep you on schedule.
It works in two steps. First the days left are converted into available study days: whole weeks each contribute your study days per week, and the leftover days are added without exceeding that weekly figure, so 30 days at five days a week becomes 22. Then the remaining lectures are divided by those study days and rounded up. Rounding down would leave lectures unwatched at the deadline, so the number shown is the pace that always finishes in time.
Add the average length of one lecture and you also get watch time per study day and total watch time remaining. Playback speed divides the lecture length, so a 45 minute lecture at 1.5x takes 30 minutes; the lectures per day figure itself does not change. Remember that practice problems and review are not included, so treat the watch time as a floor rather than your full study load.
Frequently asked questions
Rounding down or to the nearest whole number leaves lectures unwatched at the deadline. Rounding up means that watching exactly this many each study day always finishes the course within the time left.
Most people only study on some days, such as five days a week or weekends only. The days left are split into whole weeks, each contributing your study days, and the leftover days are added without exceeding that weekly figure.
Lecture length is divided by the playback speed to get real watch time, so a 40 minute lecture at 1.5x takes about 27 minutes. The lectures per day figure itself does not change with speed.
