Bonjour à tous! I am a French native that traveled the world most of his working life and witnessed how learning languages helps opening new doors. I propose you today to learn French with me. I already taught French for few years while I was in Japan and would love to help you progress in it! I always try to make learning fun and keep the mood relax. If you have a favourite subject or an interest in something, don't hesitate to share and I will articulate the lesson around it. Please send me a message if you have any question. Hope to see you soon!

Do you want to study medicine in Italy? Support for Medicine entrance Exam in Italy
I have worked for 5 years now with high school kids interested in studying medicine in Italy (both in italian or English) I believe that the key for a successful preparation of a challenging test such as the medicine entrance exam is exercise, in fact I believe that is crucial to start the preparation with an adequate advance to gain confidence with the standard exercises we can find in the exam. My lessons are based on mock exams: we go through them together seeing what are the student's gaps and then reviewing the theory of those gaps. I also believe that my method I successful since I can relate to the fear and anxiety a student preparing such a stressful exam is living, having prepared it not so long ago. Every lesson we go through a subject so we can focus on the hardest topics in every subject.

Biology and Chemistry: Secondary education - private lessons.
Need help with geography, biology or chemistry? As a civil engineer, 31, I am happy to help you! Learn at your pace and with many examples to clarify the learning material. I have years of experience in learning simple and complex material. The lessons run as follows. First, we look together for the student's biggest stumbling blocks. These can be related to the subject matter as well as to the study method. From there, I work at the pace of the student and encourage them to ask as many questions as possible. I also give tips and tricks, and improve their working methods where necessary. During the lesson I give many examples to make the subject matter more interesting and we solve exercises together. Once practiced from the lesson, I mastered challenging exercises to also test the deeper understanding of the subject matter. In this way I try to optimally prepare the student for his/her exam test. However, learning should also be enjoyable. That is why I always strive for a bond with the student through a spontaneous and positive approach. I am also very patient. All this to solve and improve the problems. Are you interested? Don't hesitate to receive me! Please come! Timo
