The Psychico College High School Expedition was successfully held in Belgrade from April 7 to 11, 2025. A total of 108 High School students, accompanied by their teachers, visited the Serbian school Savremena-Gimnazija and the Hellenic School of Belgrade. As a gesture of support, the High School Student Community donated technical equipment to the Greek school to enhance its educational resources.

The students also enjoyed guided tours of Kalemegdan Park and the Belgrade Fortress, the Nikola Tesla Museum, the Museum of Yugoslavia, the Royal Palace, the Church of Saint Sava, and St. George's Church in Oplenac, gaining a deeper appreciation for Serbia's rich history and culture. They also explored the heart of the city by strolling through the picturesque Mihajlova and Skadarlija streets, taking a cruise along the Danube river, and discovering the modern urban development of the Belgrade Waterfront. Finally, they were hosted at the White Palace, where they were treated to traditional Serbian music.

The school delegation was led by High School Deputy Director Athanasia Anagnostou and included teachers Vasilis Mitseas (Headteacher), Eirini Baladaki, Vasilis Dimopoulos, Vasiliki Karkantzou, Maria Liatou, Katerina Nikolaou, Elena Skaventzou, Giorgos Souliotis, and Christos Zikos.
