I am really thankful that there are these tutors to help, but sometimes my teacher shows a different way of showing work on my math problems, and not all tutors know the show work my teacher shows, which kind of is sad, since if I don’t know how to do the way my teacher shows I’d lose quite a bit of points on my tests and quizzes. Not blaming the tutors.
