Grade book project

I'm excited for this project because I've never used Excel before. My mother is required to create spreadsheets for her job and she always raves about Excel and the ease of it but I always preferred to create a table and fill in the data, which can easily become time consuming. I always imagined that I would use an actual grade book and manually fill in and calculate students grades. Now that I think about it, I would be very time consuming to do that for 20+ students for every project and homework assignment. It would be a lot easier to have Excel do the computations for it.
