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.

Ioannis the one of best professionals. He is very patient and knows exactly how to help his students.

Yannis's mastery of Power BI is nothing short of exceptional. His deep understanding of DAX, Power Query, and data visualization principles enabled him to create comprehensive and insightful analytics solutions. However, it is his ability to convey complex concepts in an easily digestible manner that truly sets him apart. Yannis designed and led numerous training sessions and workshops for our team, effectively translating his extensive experience into enriching learning experiences. His teaching style, which combines hands-on practice with real-world examples, significantly accelerated our team’s learning curve, and empowered us to leverage Power BI’s capabilities to the fullest.

Ioannis is an outstanding mathematics tutor. I saw significant improvement in my math understanding. He personalizes their approach, simplify complex concepts, and inspire a genuine love for math. Highly recommended!

Well, I am going to talk about my relationship with Ioannis, as due to my own choice I have chosen a full everyday life and I didn't always have time for lessons or reading. Ioannis and I did maths, and I have to say that it seemed like a undiscovered language 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, Ioannis taught me a lot of things, as he is generally busy and helped me in a plethora of fields outside of mathematics. As a person, he is open-hearted and does not hesitate to share the knowledge he has spent countless hours to acquire. 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 Ioannis, it is very important to constantly invest in your education, because this is what will give you an advantage in the future in and your professional life career.

I am 51 years old and decided to extend my studies even now. I found Giannis through this page. I carefully read his reviews and at first I was impressed by the many good reviews he had. But when I got to know it in practice, the good image that had already been created for me multiplied. First of all he is a noble man, cultured and friendly. I started teaching Macroeconomics and was literally in the dark. After about 10 hours of class, to my surprise, I found myself perceiving and analyzing financial conditions that I could never have imagined. It has modern distance learning systems, it is consistent and its communicability is inventive. Of course, I continue teaching with him in other courses as well, since I just finished the Second Semester. I think it is one of the best choices one could make.

Ioannis has been an incredible addition to my cousin's educational journey. His first lesson was nothing short of magical; he managed to make math engaging and fun, which is no small feat. Yannis's unique ability to connect personally immediately and put my cousin at ease and his warm and friendly demeanour created a fantastic learning environment. He is impressive, and he explains complex concepts with clarity and patience. We're excited to continue learning with Ioannis, and confident that we've found a teacher, mentor, and friend in our educational pursuits.

Very skilful teacher. Just in 12 hours I accomplished my goals. Thank you Yanni.

John is one of the most hard-working and kind-hearted persons I have ever met. He knows how to teach maths in a very student-friendly way while he also respects maths as a science.

I hired Ionnis to help me with some math courses (i suck at math) that I am taking in university, and honestly, my experience was amazing. He is a great teacher! i highly recommend him!
