Can Word documents from Mac be opened in Windows? I received MacBook Air for Christmas. I am a university student, and use Word for essay writing. It seems that this MacBook has 'Pages'. I post my essays online through a specific way, as they calculate if my work is acceptable etc. I don't know if my lecturers will be able to open the essay documents, especially if I've typed it from this laptop. 

Is there any way I can make sure they will be able to access my work? Do I need to buy specific office sources, or will this be ok to use?
Knowing that you are a student, you can download Microsoft Office for Mac for free from the Microsoft website (only your university email address will be necessary). 

This will provide access to your work from your new MacBook Air.
