A private teacher, also known as a TUTOR, is someone who provides one-on-one instruction to students in a particular subject or skill. They are often hired by parents to supplement their child's education, or to help them prepare for exams. Tutors can also be hired by schools or universities to provide additional support to students who need it. Private teachers are usually highly qualified and experienced in their field, and can provide invaluable guidance and support to their students.
