I used the spreadsheet offered through GoogleDocs for this project. I highly recommend GoogleDocs for any student that needs to complete a school project. They offer spreadsheets, presentations like PowerPoint, and documents like Word.
I have used this tech many times and will continue to use it for my school projects. The really great thing about using GoogleDocs is that you can share your project online with your group members too. This is helpful when you need to colaborate with a group and need to make revisions.
I will very likely use this tech again to help me budget for other things. Now that I have practiced using it I feel more comfortable using the formulas to calculate figures for me and it was really easy. Google has many tutorials for each of the docs you can create and I suggest users that are interested in GoogleDocs to look at those.
