Ioannis helped me with Quantitative Methods. He's a mathematician with huge experience in a variety of fields and I am really lucky I have chosen him as my professor.

I needed Mr. Beka to guide me in analyzing data, setting up my models and developing algorithms to draw conclusions about the efficiency of specific hospitals in our country. We do 3 hours a week, and while the financials made me a little hesitant at first, I soon realized that the quality and speed of the course is 100% worth it. He takes out a large piece of matter in a short period of time and with great accuracy. Totally satisfied.

Well, I will talk about my relationship with Giannis, as due to my own choice I have chosen a full everyday life and I didn't always have time for lessons or reading. Giannis and I did maths, and I have to say that it seemed like Chinese to me at first, but through a few hours and a lot of patience on his part, I succeeded and scored a very respectable grade. Now, beyond the lessons and as a person, Giannis taught me a lot of things, as he is generally busy and he also helped me in matters outside of mathematics. As a person, he is open-hearted and does not hesitate to share the knowledge he has spent countless hours acquiring. To those who hesitate because of the price, let me tell you that what you will get in return is worth much more and as I learned from Giannis, it is very important to constantly invest in your education, because this is what will give you an advantage in the future in your professional life his career.

Ioannis is one of the best professional that I ever came across with. He “builds” lessons according to his students needs. He is very communicative and helpful. I strongly recommend him.
