FAQ
How are weighted grade categories calculated?
Each assignment score percentage is multiplied by its relative category weight, and the sum of all weighted scores is divided by the total sum of weights to produce an accurate overall percentage.
What letter grading scale does this gradebook follow?
It uses standard North American secondary/university letter intervals: A (93-100%), A- (90-92%), B+ (87-89%), B (83-86%), B- (80-82%), C+ (77-79%), C (73-76%), C- (70-72%), D (60-69%), and F (<60%).
Is student grade data stored on external servers?
No. All student names, scores, and statistics are computed 100% locally in your browser memory and are never uploaded or transmitted to any server.
Can I export the grades for administrative record keeping?
Yes. Click the "Download CSV" button to save an organized spreadsheet compatible with Microsoft Excel, Apple Numbers, and Google Sheets.
