As always horses for courses! Cambridge Home School (CHS) is in our view the only choice for discerning families with high ability children. We tried Interhigh (disaster - classes of over 300 say no more!) and Myonlineschooling (mediocre at best - no homework, low standards, poorly qualified staff) - it seems to us that you really do get what you pay for I'm afraid. Simply put we can't depend on these 'schools' to provide our children with the same opportunities that their previous private schools could provide; highly qualified teachers from top Universities, small classes, similarly motivated pupils coming from similarly motivated goal-driven families, networking for the future, access to top unis etc. Cambridge Home School does provide these opportunities and at a fraction of the fees, we used to pay. So for us, it's extremely good value for money and the only choice. For those on a budget and children who are less academic, the other two might be an option of course and far cheaper than private tuition. Ah and the Wolsey hall, Oxford home learning thing, steer clear! They say they are a school but they're not - glorified textbooks, no lessons and a helpline! My kids are super motivated but they at least need lessons and a teacher!
