ISSOS has been an amazing experience. I had the opportunity to attend to Cambridge and Yale´s summer courses. It is amazing how you incorporate with people from all over the world, how the staff treats you is absolutely amazing. "An experience of a lifetime" could not be more accurate, those six weeks I spent on the course were one of the best days of my life. Unfortunately I am turning 18 in May, so I won´t be able to attend to St. Andrews. But if I had the opportunity, there would be no doubt I would participate again. I had recommended friends to participate in ISSOS, and most of them are willing to do the same courses I did when I had the opportunity. ISSOS was totally an experience of a lifetime, there isn´t any moment I don´t smile when I see my certificate of my two courses. I am really thankful that I had the opportunity to attend, I really hope that people who may attend to your summer school don´t hesitate on their decision. This is a 100% go situation. I am still in contact with my friends I made, it is amazing how you can establish a lasting friendship in just 3 weeks. I am very grateful that I had the opportunity to attend, I will never forget this experience whatsoever. When I grow up and have my own kids, it is certain they will attend the three courses, 100% guaranteed. To conclude, I am very thankful to all the staff members both in Cambridge and in Yale, they were absolutely amazing. I really hope there will be a chance to see you again in the future, I would have loved to attend ISSOS one more time. I had the experience of a lifetime, THANK YOU. Hope to see you in the future.
