are your parents helping you and if so is their car reasonably spacious?
you want to pack things you always need (clothes, but not the ones you dont wear anymore, etc)
you may want to pack things you're going to need (eg kitchenware) but you can always buy this on arrival
you could pack things you don't need but might want (eg random personal things like walking boots) but you may decide you wont be needing these things
just a few pointers
