Joe’s exam paper solution books are worth getting for your children. My son did Ordinary level maths and his friend did higher. Both kids found the books a huge help as they are written clear and concise. From a parent’s view I found Joe’s Facebook page extremely useful. He answers your questions promptly and is very helpful. I learned more about exams, college applications etc from Joe’s page than anywhere else. If every teacher took as much interest in their students as Joe does maths would not be an issue.
