I need a patient and experienced math tutor to help my 16-year-old son improve his understanding of algebra and geometry. He is preparing for his GCSE exams and struggles particularly with problem-solving and applying formulas. Ideally, the tutor should be able to provide clear explanations and practical examples. Sessions would be twice a week, focusing on building confidence and exam techniques. We prefer someone who can come to our home in the evenings or offer online lessons.
