ave been always finding my self teaching my friends and classmates. In high school, . Our teacher asked me to help my friend with studying; she told me: "I can't help him as you can, you have an amazing way to deliver materials for students, please your friend needs your help!". I accepted and helped him in Chemistry and Arabic, then he passed them all successfully! I was very proud that I could help a student pass his exams. However, it was not my first time in tutoring, I have been always helping my classmates during exams whether in School or in College. Later on this year, I also helped another friend of me in English and Math. He likes my way of teaching very much, and his parents told me: "He doesn't study well usually but only with you". I feel I can help students because I am a student like them in the same age and I know their way of thinking. I hope I can help students as much as I can to pass successfully their exams and improve their knowledge.
