hello, I'm a professional in the field of mathematics where I have a so much experience in this field. when I was in high school I started tutoring kids that are like from grade 4 to grade 7, then when I reached third-year secondary I started teaching students that are from grade 8 to grade 10. after I reached university, I started building up my teaching experience when I taught in a school near my valley, I helped some poor students in learning for free (not only in mathematics). In addition, when I reached higher levels in my studying I started teaching people who are even in university. Guide students through practice problems for math classes, answering any questions about concepts or next steps Create lesson materials to improve memory, including flashcards, practice quizzes, and supplemental instruction (worksheets, videos, etc.) Edit homework assignments, point out big picture problems to have student edit their own work Teach techniques for focusing. Even in the pandemic, I kept using the same ways of tutoring and dealing with students. Moreover, AI am teaching on a website called studypool where I help students with their assignments and exams from different countries and delivering them the best quality solutions
