I am a 5th year medical student at Université Saint- Joseph de Beirut (USJ) in Beirut, ranked between the top of my class. I graduated from highschool with a french baccalaureate, being the first of my class with an average of 18.02 (in life sciences).
I am passionate about teaching, and most importantly, helping the students to find a way to understand and study on their own (by giving them some tricks! ). I think that each student has it's favorite or most effective way to learn and study, and one of the tutor's duties is to help him/her find this way.
I have 5 years of experience in freenlance tutoring , as well as tutoring with some local agencies. I gave courses for the lebanese, french and international baccalaureate, as well as group sessions for the entrance exam for medical school at USJ.
I am more comfortable with teaching scientific topics for all grades, or even biology or medical related classes for university students! I can teach in French, English or arabic.
