First year uni student who took GCSE and A Level maths looking to teach maths to 11+ and GCSE maths students

Can do Private 1 to 1 lessons with maths students who are struggling to understand concepts in maths or struggling in school exams and want to achieve higher grades. I have a lot of experience in maths as I have taken the 11+ for grammar school and got into one of the best grammar schools in Birmingham. I have also taken GCSE maths and A Level Maths and achieved Grade 7 and Grade B respectively. I have previous teaching experience teaching mathematics, economics and computer science to younger students at school as part of mentoring and teaching opportunities and have a great passion for teaching and sharing knowledge in a way that students can understand easily and can become confident enough to answer questions on topics they were unsure on before and eventually get good grades in exams
