I have been taking lessons with Yilmaz since BOSC 1, and I can honestly say he has been incredibly helpful throughout my studies. He is patient, supportive, and always makes sure I understand the concepts rather than just memorising them. He explains things clearly, adapts to what I need help with, and genuinely cares about helping his students improve their grades and confidence. I would highly recommend him to anyone looking for extra support, especially with Revenue Management. He has been a great help to me, and I am very grateful for all his guidance!

I’ve been taking tutoring sessions with Yilmaz since BOSC 1, all the way through BOSC 3, for all my subjects at EHL, and I can honestly say it has made a huge difference in my studies. Thanks to his help, I’ve consistently achieved excellent grades in my exams, and I always felt confident and well prepared going into them. Yilmaz is not only extremely knowledgeable, but also incredibly patient and dedicated. He takes the time to explain everything clearly, provides all the necessary study materials, and makes sure you truly understand the topics rather than just memorizing them. Even with his busy schedule, he always makes an effort to find time for his students and is there whenever you need help. I’m really grateful for all his support over these three semesters. If you want to feel confident going into your exams and achieve great results, I genuinely couldn’t recommend a better tutor!

I’ve known my tutor for a while now, and he has really helped me understand concepts that I initially struggled to grasp in class. I really like the way he explains things clearly and guides me through each step, helping me understand the reasoning behind every exercise. He is patient, approachable, and always willing to help. I feel comfortable asking questions, even when I need something explained more than once. His support has made me feel much more confident in my studies. I would definitely recommend him!
