This is a timed drill for the multiplication tables 1 through 12. You pick a table, work through problems against the clock, and every answer is scored immediately as correct or wrong. Each session feeds an accuracy score kept separately for that table, and a progress chart shows how the twelve scores have moved across sessions, so a genuinely weak table like the 7s or 8s shows up as a visible dip in the bars. The surprise for most users: drilling one table changes nothing about the others, and your history lives only in the browser where you practiced.
A concrete input and expected output from the current implementation.
Input
Session on the 7s table, answers entered as each problem appears: 7 x 8 = 54, 7 x 3 = 21, 7 x 9 = 63, 7 x 6 = 42, 7 x 4 = 28
Expected output
5 problems answered, 4 correct, 1 wrong. Accuracy for the 7s table: 80% (4 of 5). Missed problem: 7 x 8 = 54 is incorrect; the product is 56.
Each answer is scored as it is entered, so the only miss is 7 x 8, and accuracy is correct answers divided by total problems (4 / 5 = 80%). The result is recorded against the 7s table alone; the other eleven tables' scores are unchanged.
Choose one of the twelve tables and a timed session begins with the first problem. Problems appear one at a time and each answer is scored as it is entered, so a slip is visible immediately rather than at the end of the run. When the time window ends, the answers you managed to enter are tallied: correct answers divided by problems attempted becomes the session's accuracy figure.
Every finished session adds one entry to the history of the table it practiced, recording how many problems were attempted and how many were correct. The progress chart draws each table's accuracy across its sessions, so a table that stalled shows a flat or falling series while an improved one climbs. The history is kept on the device, in the browser where you practiced, and reappears the next time you open the page.
No. The progress chart is stored in the browser where you practiced, not on an account, so a different device or browser starts with an empty chart. The same browser on the same device still shows your full history the next time you visit the page.
No. The drill runs entirely in your browser: problems are generated, scored, and stored locally on your device, and nothing is sent to a server. There is no account to log into and no sync between browsers, which is also why clearing site data or switching browsers erases the chart.
