I have honestly not worked with Excel this much since I was enrolled in the required high school computer literacy course. The functions were not difficult to figure out, with the assistance of the "help" button... After I remembered the initial '=' sign, it was all up-hill. I was unsure where exactly to position the new data, so I just included it in the columns below the original information. I really needed this refresher on Excel, especially with the possibilities of recording such data in the future (grades, too).
Excelling in this course!
