Mathematics and physics-chemistry are the most important and most requested subjects, with me you will become familiar with these two subjects especially if it is in English, and yes, I can teach them in English since I master the English language and also I study Exact Sciences and Sciences for the Engineer in bilingual (but 80% in English). And as today's world is very connected, I could teach you the basics of Chinese and also you will have fun with the Arabic language with its all dialects and its beautiful calligraphy with Chinese. For science, courses are intended for students from primary to high school. For languages, the courses are intended for everyone.
