“Mr. Vaczi has a very unique way of teaching, he always began his lectures with positive videos and quotes that literally applies to the period that i'm living now as a student. He is always there for a help, not to mention that he is a very caring and kind person. His attitude and behavior is very professional and polite. He explains the subject with real life examples and how important this subject to us and our society. He is the best teacher a student could have!.”
