Don't hesitate to do exchange studies! It is such a rewarding experience that we are offered ! You definitely learn how other universites and countries work within the field of interest, which I believe is an important insight if one wants to work internationally in the future. Since the medical research is global, I think it is of great importance not to be narrow-minded. Exchange studies definitely widens your view, which I think is a merit for the future career.
