Hello, I would like to ask you some questions relating summer programs in physics. I have applied for several programs this year and one by one, I am being rejected in all of them. I don't know why this happens, my marks are really good, and I have studied four courses of the physical sciences career in only two years. Moreover, I have some aditional diplomas in java and C# programming. My referees are not bad, indeed, I have two senior referees. I don't know what to do, so I would like you to give me some tips, maybe I am doing something wrong in my applications. In adition, It would be great if you told me some summer programs in physics for undergraduate students. Thank you.
