D’une très grande aide, rapide et efficace, un très bon prof.

I highly recommend Mr Theodor as a teacher both for university exams and for professional development. My collaboration with him was good and the courses were held smoothly, which ultimately helped me to achieve the expected results and to train my skills in mathematics and finance.

Theodor is very knowledgeable and knows how to explain complex concepts well. He goes through examples and encourages the student to ask questions and spends time going through the material without rushing it. He is very punctual and has excellent communication skills.
