On the Class List tab you type each learner once: admission number, name, class and gender. On the Marks tab the subjects run across the top (rename the yellow headers to your own) and the learners run down the side, pulled in from the class list, so you never retype a name. Enter the marks and the Total, Mean %, Grade and Rank columns fill themselves in. The Grading Scale tab holds the A to E bands and the pass mark, all in yellow cells you can edit to match your school, so the grades follow your own policy rather than ours.
The Subject Analysis tab shows the class mean, the highest and the lowest mark for every subject, so you can see at a glance which subject carried the class and which one pulled it down, and the Term Report prints one learner's marks, grade and position on request. Yellow cells are the only ones you type in; every other cell is a locked formula, so a busy staffroom cannot break the maths. It opens in Excel, WPS or Google Sheets, so you can mark from a phone. The premium upgrade adds a class dashboard with bars, a printable report card per learner, term-on-term progress and Swahili labels.
