Hi Rachel,
Here is a link for free download, it's called open office. This is what I had in my other computer. It was excellent, free and no bugs.

Before you download, you can look at the video so you can get an idea of everything that you can do with the software. Let me know what you think.
Hope this helps! Wish you luck in your studies!
Liza
