This is a plan book that you can use for either Excel or Google Sheets. I use this on Google Sheets because I can easily pull it up at home (it's online) so I can make changes if need be. I also enjoy Google Sheet's fonts better than Excel's choices. It's currently formatted with my schedule =P, all you have to do is change the times and subjects to match your own. To add a new week of plans, duplicate the original tab (on the bottom of the screen) and rename. Happy planning!
