Anyone who has a 1st class Honors degree in Maths, regardless if from NUS, UK Cambridge, or US MIT, should be snapped up immediately. To many students at all grade school levels, maths seemed daunting, but in reality, it is the ROOT or principles which are actually very simple to impart by teachers, but sadly, somehow along the way they failed to do so, & complicated the entire process of logic which Maths is built upon.
The 'mother i learnt from' would make a good tutor, as to get the honors degree, she would had understood such principles & will be successful to impart such to her students & help them not just score, but inculcate the principles of logic to them which are critical & needed in the real world we live in.
