I've spend my weekend revising.
You would not believe how good and effective Microsoft Onenote 2007 is for note-taking and revising from. It is amazing.
My friend got a MS Office 2007 Enterprise CD from University and apparently he has a license to install it as many times as he wants, so I thank him for that.
I tried the other MS Office 2007 products (word, excel, ect...), didn't like them, popped the Office 2007 CD in, and then the Office 2003 CD.
