I attended the Hungarian Computer Science program at ELTE.
Overall, I think that it is among the top 3 computer science & engineering courses in Budapest, however it still some flaws.
The general quality of education is high.
The teachers are very nice, even friendly, and very helpful (only very few exceptions!)
If you want to learn computer science by a more theoretical & math-focused approach, this is the best university in Hungary to do so. If you would like to learn about hardware, IoT, embedded systems, or if you are interested in engineering & physics, this is not as good as f.e. BME.
The greatest flaw that I saw is that the curriculum really hasn’t been changed for the last 15 years. In 2008 it has been transformed, but most of the subjects stayed the same. Therefore I had to learn many technologies that were awfully unhelpful and unusable, but we didn’t have time to approach topics that my friends at other universities in other countries examined in depth.
PLEASE NOTE THAT THE ABOVE POINT IS ONLY VALID BEFORE THE 2018 CURRICULUM CHANGE, OF WHICH I HAVE NO EXPERIENCE.
