has anyone ever gone on these programs? I was going to go this summer on the med. discovery, be it's $5000 and my parents are making me pay for 1/2 of it. I am re-applying next year, I have about $800 saved already Does anyone know of how someone else funded their trip, suggestions for raising $$$? (I am 15, so I can't get a job)

My son was invited to join and go to Australia, but we couldn't afford to send him. :(
