I believe a tutor should have experience in the subject they are tutoring for.
Explanation:
I believe a tutor should have experience in the subject they are tutoring for because it's important for the tutor to understand the concepts they are trying to teach. It would be harder if a tutor just wings it, and teaches a student about a concept they know nothing of. Furthermore, it's also very hypocritical. The student might think, 'why is someone teaching me about something they don't know?' The tutor isn't going to help the student get any better, and the tutor isn't getting any better by teaching something they don't know anything about. Therefore; it is important and essential for a tutor to have substantial experience in the subject they are tutoring for.
This is false because if your tutor is not experienced in the subject that you need extra help in then they won't know how to help you since they haven't educated in that subject.
