Qualified Mathematics Teacher for 11 - 18 Year Old Students in the UK. Have been a teacher for 8 years providing a great opportunity to teach all age groups of varying abilities. I was recently appointed by a school to specifically work with their higher flying 15/16 year olds in preparation for their GCSE Examinations. I have also been working with less privileged students through a mentoring scheme in order to help 'narrow the gap' in achievement.
