I am a student of GESCO and my experience in ESIC is generally good. As I have not previously studied Marketing or ADE, I am quite learned. Meanwhile, colleagues who have already completed these courses claim that there are some teachers who do not contribute much new knowledge. I generally miss that teachers share more their professional experiences, something that is expected of a business school, and that more practical cases are applied to further internalize the theory. There are however some very good teachers who have shared many experiences and the class was very helpful.
