Here is a quick tip for those who need to make a PowerPoint presentation but don't have the software. You can use Google Drive to create a presentation. Just go to Google. Click "Drive," which appears on the black toolbar at the top of the webpage. Locate and click the "Create" button on the left hand side. Then, scroll down to "Presentation." Now, you can create a PowerPoint presentation without having to buy or locate a computer with the software.
Hope this helps!
