Maths for GSCE and AS Level

I have being tutoring various students Mathematics for over a year in person and in one case the boys mark went up from 48% to 72% in the space of 12 lessons. I love helping people learn and seeing that lightbulb go off. I am currently studying a finance degree and completed one years worth of Maths at a university level. I have a constructivist teaching approach where I believe that Maths is best learnt through me guiding them into them being able to understand the work rather than just being instructive.
