So you will want to enter your symbols on this Excel spreadsheet. Enter them once and only once, and do not change them once they've been entered. I will copy and paste them into my own gradebook once I see they have all been entered, so any changes you make will NOT be reflected in my copy. Give your absent classmates 2 full class days after the workshop to get their notes to you. On the third day, if they have not provided you with the notes, you should enter a goose egg (that is, a zero) for their notes.
