gap year is just a period of time spent of during study, usually between the finishing of yr 12 and entering uni/college. I personally would take a gap year however time is not on everyones side. there are many benefits to gap years and you can find them here

thanks , i thought gap year was like taken when, for example, your not sure whether u want to go to uni or not, or travel or whatever, and so u typically dont study during 1st yr?
not necessarily, if you don't want to take a gap year that involves travel you can do anything else between your free time between yr 12 and uni. it is completely up to you what you choose to do in that available time. however travel seems to be the best way to spend that time.
