Participants' Impressions

Hear from the participants of our Summer Camp in Romania in 2024

Alejandro Vivero
International Olympiad in Informatics (IOI) Gold 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."

Eliška Macáková
International Olympiad in Informatics (IOI) Gold medal, International Mathematical Olympiad (IMO) Silver 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."

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

"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!"

Romania
Timur Degteari
International Olympiad in Informatics (IOI) Silver medal, International Mathematical Olympiad (IMO) Bronze medal

"The camp was amazing. I'm really happy I managed to attend it in my last high-school olympiad year. Everything was organized and made really well, starting from lectures and prepared contests till the free communication with organizers and fun events and activities. I would really love to attend the next edition of ACTS if I was given a chance, and so I would recommend it to anyone. One of the best events in my life."

Moldova
Nemanja Majski
International Olympiad in Informatics (IOI) Silver medal

"It was quite fun. I got to meet a lot of other competitive programmers from the region. We played board games, talked, solved problems together and overall it was quite nice. Feels like an IOI before the IOI. Lectures were nice too. I definitely recommend applying for the camp."

Serbia
Simon Bachran
International Olympiad in Informatics (IOI) Bronze medal, Central European Olympiad in Informatics (CEOI) 2024 Bronze medal

"I really enjoyed the ACTS camp and I would definitely go there again, if only I hadn’t already graduated. Besides the various contests and the compelling and well-taught lectures, I also learned a lot about Romanian history and culture and made very good friends from all across Europe.

I really liked that you were able to choose the lectures/contest for each day individually depending on your preferences. That way I feel like the ACTS camp was a great preparation for IOI and maybe future CP contests. It was 10 days, I couldn’t have spent on training more efficiently."
