Our family has been using conquermaths for several years and for different levels. The lessons are clearly laid out and progress sensibly and give a thorough grounding in mathematical principles. Once a child is computer-able they can be fairly independent in using the course and if they do get 'stuck' I find that if I watch the lesson I can assist through the problem (my maths is not as good as it could be so I need to jog my memory first). We have used this system in primary age, KS3, GCSE and A level and with 3 different children. I feel it is especially useful once your child is KS3 - 11 - 14 - as it builds confidence for the coming exams and allows independence and visible, measurable progress without 'breathing down the child's neck'. For those home educating it is an essential resource.
