When I was in elementary school we had this program called GATE and basically it was like once a month you go to a different school with other GATE students from the other schools in the district. There would be special classes like oceanography, robotics, etc. I don't think it added any value into my life ever except variety of experience. I also think it made other students who weren't in it feel kind of bad because they didn't get to go do anything. They should have just done it for everyone IMO.
