Polytechnic University of Bucharest is suitable for people who have completed a high school or technical high school. The studied subjects are quite difficult at first, but it depends on the chosen profile.
I have graduated from the Faculty of Mechanical Engineering and Mechatronics, the Industrial Engineering Department, specializing in Industrial Design. It was an easier specialization, but I was expecting more.
Every semester we had a new design program, but we did not deepen any of them.
Teachers are ok, they help you when you need them. You can take advantage of Erasmus scholarships for both study and practice. I have been practicing since year 3 in Malta and it has been a wonderful experience.
