Upload a coordinator gradebook (.xlsx) with one or more sections. The tool detects sections, activities and their elements, then computes CO attainment per student, per section, and for all sections together — entirely in your browser.
No file attached
Each section starts with an ID row (followed by Course / Instructor / Section / Campus …), then a header row beginning with #.
Activities are read from headers like Midterm(35.00%) — the percentage is the activity's weight in the course grade.
An activity with a single Total column has one element; an activity with columns 1 (/30), 2 (/30), … has one element per column (the Total column is not used).
Students with a Withdrawal/Awithdrawal status, or with no grade in the final-exam activity (marked *), are excluded automatically.
