hi, aside from the fact that I live literally Less than an hour away; as a previous tutor of six years, student of psychology and a writer, I can confidently say that I have the right abilities, tools and resources to help your son achieve the targeted grade or above depending on their willingness to learn. I have a proven track record and have taught classes as high as A Level & currently hoping to pursue a master's in social psych. DBS checked, but may need to check for in date eligibility.
