I was excited to participate in this summer school - I just can't get enough of mathematics! This programme was great in almost every aspect. I loved attending the classes; they were challenging, but that only motivated me more, as it felt like we were expanding our mathematical thinking. I also really enjoyed the full experience. Including the extra social activities allowed us to connect with people from around the world!
