Deadly! Very knowledgeable on the subject matter. If he does not know something, he will either look it up or derive it from first principles. Very patient in explaining advanced topics.

Deadly! Yannik is truely a "superprof". I have been working together with him on a very advanced Econometrics project. He is great at breacking down complicated statistical concepts and putting them into practice. I can highly recommend his lessons.

Deadly! Exceptional and brilliant math tutor - able to engage and teach math in a way to engage even the most challenging learner.

Deadly! Do not let the cost deter you. Yannik is incredibly helpful, patient, and, most importantly, knowledgeable. I highly recommend his assistance!

Deadly! I was hesitant to book Yannik at first given the cost, however, without a doubt Yannik is worth the cost and more. The value for the knowledge gained is unmatched. I am currently taking statistics at Columbia Business School. Yannik was able to break down my material in a simple and understandable format that allowed me to grasp the material and not just simply follow along. I highly recommend Yannik, you get what you pay for here!

Deadly! I really appreciate Yannik's responsiveness and professionalism. He always helps me understand the most difficult material in my math classes and I seem to really understand the material better. This is probably because he doesn't rush and explains his reasoning very clearly. Best tutor.

Deadly! Yannik is the best tutor for stats and other math problems. He's very accommodating to my individual learning pace, and does well to try and understand my strengths and weakness. His approach is always to verify that I understand each concept in a problem without just giving me the answer, which is what some tutors do to save time.

Deadly! For the introduction with me and my son, Yannik’s attitude was as we’d hoped. Yannik was clear and concise with his approach and method but most of all he was able to connect with my son as others haven’t and implemented my son’s interest and enjoyment of soccer to support math concepts. My son is excited for upcoming sessions and look forward to working with Yannik. Jackpot to us and highly recommend

Deadly! First tutoring session en great. Qualified and takes time to explain.
