Economics for Leaders for an international student

Hi, I’m Shafkat from Bangladesh, and I’m currently in the 11th grade. I wish to attend college in the USA, so I’m looking for good summer programs. I had applied for the FTE Economics for Leaders program, and was accepted in my first choice(Yale). Is this prpgram really selective, and is it worth attending? Will this add value to my college application(I wish to study economics). Is it worth the expense and time, provided that I’m going to have to travel half way around the world? Thanks in advance!
