     These days, more and more students in the UK are taking a "gap year" between their graduation

from school arid their university studies. This means that they take a year off, to do something else,

before they start their studies.

     For most students,  spending time in foreign countries is the favorite activity-and Australia is the

favorite place to go.

     Many parents,  teachers and business people agree that traveling can teach important values.

     "After a year of travcling, I felt I'ci grown up. I had learnt the importance of relationships with people, 

on all sorts of levels. "

     There arc many companies around the world that welcome these students on their projects hclping

people in poorer countries, or even in your home country.  Although you don't get paid for your work, 

this

kind of work can teach important skills-decision making and finding answers to problems.  for cxample

that will help a student in a job one day.

     Finally,  getting some knowledge and experience in an area you hope to study or work in one day

will always bc very useful.

     If several university graduates are applying for the same job, gap year work cxperience allows you

to say:  "I've already had some experience of this kind of work. "

     And that can get you the job!
