Prior to June 2010 licences were issued on a permanent basis. Starting June 2010 licences are issued as short term subscriptions for three years or less. This allows schools an immediate reduction in startup costs.
Each MathBase package (1 to 6) can be licensed individually either for whole school use or for a specific number of users. There are discounts if the school uses several packages - they do not (no longer) have to be purchased at the same time.
Prices below are for a three year subscription and exclude VAT. Annual subscriptions are at one third the cost. Postage and packing are free within the UK.
