Testimonials

"What I loved most about the ACTS camp was the wide range of the courses: from machine learning to proving math theorems with code, each lecture presented was always something challenging, something new to learn. Besides the courses, you never lacked something to compete in: upsolving, IOI-style contests, and even the evening activities were competitions. All of this made it the most fun camp I've ever been to, and I really hope to participate again next year!"

Rares Felix Tudose, Romania | International Olympiad in Informatics (IOI) Silver medal

"The ACTS was an amazing camp and one of the best events I've ever been in. The teachers were excellent and a variety of lectures, both from competitive programming topics and more general informatics ones, and contests. Besides the academic part, there were several fun activities organized in the great installations we were living in.
For future participants, I would definitely recommend this experience."

Alejandro Vivero, Spain | International Olympiad in Informatics (IOI) Gold medal

"If you want to get gold at IOI, meet a lot of cool people or just win a water gun and compete in rolling toilet paper as fast as possible, the ACTS camp is the right place for you. For me, it might've been even more fun than some of the international olympiads I've been to, because you have the same friendly-competitve environment, but it's less stressful, longer, and has even more activities occupying every part of the day. I've gained lots of new memories and knowledge, and I definitely recommend the camp to everyone else."
