"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."

“I loved the atmosphere and the classes this year – seeing how informatics could be applied to areas such as biology and economics was very cool. The organizers went out of their way to make sure there was always something fun to do, from a bot-writing tournament to IOI contests and advanced (but super interesting) lectures on topics like link-cut trees, matroids, and optimizing exponential algorithms. Can't wait to see what you have planned for the summer!”

"The ACTS Camp in Serbia was the best camp I have ever been to. I enjoyed algorithmic lectures and IOI contests. Also, I really liked having lectures not only about algorithms and competitive programming, but also about cryptocurrency, Kotlin, and Bioinformatics. It was very useful!

Besides studying, I played basketball, board games, and participated in fun activities organized by the camp.”

“I have many good memories and hope to attend this camp one more time in summer. It was a great experience to meet and do all of those fun activities with other international students who are also interested in olympiads like me.”

“ACTS camp really amazed me by being extremely fun and academically useful at once. I met some very cool people there, who, despite coming from very different backgrounds, have had really similar experiences in life and think very alike. With them, we got to participate in lectures and contests, and prepared together for our upcoming competitions—some of which we’ll even attend together.”

"The camp was a once-in-a-lifetime opportunity for me. I have never been to such a fun and memorable camp. Not only did I learn new things about competitive programming, but I also made long-lasting relationships with amazing people. There were a variety of lectures and optional fun activities, where I was able to get to know others better. In addition, the location was magnificent, surrounded by beautiful villages and superb nature. All in all, the whole experience was a perfect blend of entertainment, relaxation, and serious problem-solving."
