Well, many many...years ago, there were only home tutors and not tuition centres. Our forefathers, grandparents, guardians...did not need long to decide on whom to engage.
Experienced full-time tutors often have the ability to quickly identify the weak area
faced by most children and are very familiar with the syllabus as they teach
the same subject and topic often multiple times to different students.
The right type of tutor for your child
really depends on your tuition needs and budget you are able to afford.
