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?
