I work in the electricity field and the idea that I had of the course is what I have seen. It is an introductory course to understand how light works and then you do a theoretical-technical part, making visits to companies and factories. Then there is a more practical part, where we made visits to some facilities. To sum up, it is an entertaining, pleasant and interesting course, although a little short. But I liked it. I would definitely recommend it. It is a creative course and you can work individually or in groups. It is the first time that I study here in ELISAVA and I really liked the teachers, you can see that they like this field. They are professionals who are currently working on this.
