I need to use PowerPoint for a project and my teacher said that everybody should have it on there computers, and he wouldnt help us get it on if we dont already have it 
I will get a really bad grade if i don’t use PowerPoint please help
Solution:
There is no free legal powerpoint software.
HOWEVER, go to Microsoft website and you can download a free 60 day trial of it.
at the end of 60 days…it will cease to work unless you purchase.
openoffice.org has a program called impress that is very similar, and its free. Just when you save make sure to select powerpoint from the little drop down menu where it says format.

Alternatives
There are alternatives that read and write PowerPoint files. There are two packages I’m aware of.
1. OpenOffice (Impress) is a presentation software that’s bundled with four other applications that include a word processor, spreadsheet application to name a few. It’s capable of saving presentations as .ppt files (you’ll see this option when you click File– then "Save As" an option called "Save as type" drop down menu. I’ve used it on various different occasions and have found that it works beautifully.
2. Lotus Symphony Presentations is also a presentation software that is bundled with a word processor and spreadsheet application. It’s quite similar to OpenOffice but has a very unique and different layout that may not cater towards everyone’s taste. It does have some useful features such as exporting presentation to PDF (Not sure if OpenOffice Impress has it).
Note: Lotus Symphony Suite is in Beta mode and requires a decent amount of RAM (1Gb Recommended. 512 bare minimum to get by).
