My son loves mathletics, and I'd like to get him a subscription (his school only uses it for one week a year).
My concern is he's working two years ahead of himself for maths; has anyone got any experience with this and the mathletics site? If I register him at his current year, I'm worried it'll be too easy, and I'll be wasting my money.
I'm not overly familiar with the site as I've only seen it in operation a couple of times, so I don't know if my concern is a real one or not.
