Doğan hocayla AP Calculus sınavına hazırlanıyorduk. Doğan Hocayla iki buçuk ayda inanılmaz bir ilerleme gösterdim. Konular hakkında biraz birikimim olsa da AP soruları hakkında hiçbir bilgim yoktu. AP sistemine alışık değildim hem de derslerimi Ingilizce görmüyordum. Gerek akademik(Calculus) gerek moral anlamında bana çok destek oldu. Eksiklerimi belirlememde ve eksiklerimin üstüne gitmemde de çok yardımcı oldu. Gerçekten Doğan hoca ile çalışmasaydım AP sınavından geçebilecek bir puan alamazdım.

Mr. Doğan and I were preparing for the AP Calculus exam. I've made incredible progress in two and a half months with him . Although I had some background on the issues, I did not recognize the AP questions. I wasn't used to the AP system, and I didn't see my classes in English. He was very supportive of me both academically(calculus) and morally. It helped me to identify my shortcomings and to get on top of my shortcomings. If I hadn't worked with Doğan teacher, I wouldn't have even gotten a point to pass the AP exam.

I have known Mr. Dogan for about two years.

He helped me prepare for the Scholastic Aptitude Test (SAT) exam first, and then, with my math classes after entering the college.

To me, Mr. Dogan is a punctual and attentive teacher. Thanks to him, I was able to get accepted from many reputable Universities, i.e University of Bologna Business & Economics in Italy. Now, I am studying Business Administration. Thanks to him, I passed my Calculus exam with high grades. I highly recommend him to anyone.

Dogan was a great teacher. He was always patient and explained everything in detail, and was always available for extra questions. Highly recommended
