Khan Academy is free, enormous and genuinely excellent. Here is an honest account of what it does not do — and when that matters.
Khan Academy is a non-profit offering a vast library of free lessons and practice across maths, science, humanities and more, with mastery-based progress tracking. It is one of the most significant educational resources ever built, it is free, and no comparison should pretend otherwise.
Best for: Almost anyone. If you need to fill a specific gap, revisit a topic, or work through maths systematically at no cost, Khan Academy is very hard to beat and you should use it.
If one of these is what matters most to your family, choose them. We would rather you had the right thing than ours.
Khan Academy is free. Skoolio is £29.99–£99.99 per month. If budget is the constraint, use Khan Academy — it is excellent and we would rather say so.
