What does a super-tutor do?
I personally tutor French, Italian, English and Religious Studies. You can find a tutor for pretty much any subject. It's intensive one-on-one tutoring, going over schoolwork and teaching "bonus" extra material.
Do you have to be super because the children are exceptional, or are you super because they are average but their parents expect exceptional results?
The majority of my clients are students at top private schools trying to get from an A to an A*. I probably have a skewed view of what is "average" because I work with children who are already very well-educated. My "worst" students expect to get all Bs, minimum. Some of my students agree to tutoring because of parental pressure, some are genuinely very keen to improve their marks. I don't like classifying children as exceptional or average because I've come to realise that the quality of education you have access to is far more of an influencing factor than native intelligence.
