How to use the review priority calculator
Building an error log is the easy part. Deciding where to start when you reopen it is what actually stalls a study session, and most people end up rereading the first chapter again. Enter the number of questions you attempted and the number you missed for each topic, and this calculator works out the error rate for every topic and sorts them into a review order you can work straight down.
The error rate is missed divided by attempted, multiplied by 100, shown to one decimal place. Three sort options are available. Highest error rate puts your weakest topics by proportion on top. Most questions missed favors the topics with the biggest absolute pile of questions to redo. Weighted volume multiplies the two, so a topic has to be both a high share wrong and a large number of questions to lead the list.
One caution: this order is built only from the numbers you entered, so it is a reference and not a scientifically validated optimal review sequence. What is actually on the test, how much each topic is worth, and how many days are left all matter, so treat the ranking as a starting point. A topic with only five attempted questions also swings wildly, because a single miss reads as a 20% error rate.
Frequently asked questions
No. This order is a reference built only from the numbers you entered, not a scientifically validated optimal review sequence. Adjust it for what is actually on the test, how much each topic is worth, and how much time is left.
Yes. Names like Probability and Statistics work fine. Commas are the most reliable separator, and without commas the last two numbers on the line are read as attempted and missed.
It sorts by error rate multiplied by the number missed, so topics that are both a high share wrong and a large pile of questions rise to the top.
