If you are an existing KooBits user buying 1 or 2 more subject(s), your current subject subscription will be extended and the new subject(s) will be added. The new subscription (which includes all these subjects) will end on the same date.
Sample illustration:
- When a KooBits Math user (into 3 months of annual subscription) buys the KooBits Science subject, the value of unused 9 months of Math subscription (pro-rated* based on what was paid previously) will be used to offset the new subscription price. After payment, both Math and Science subscription will start and end on the same date as a 1-year subscription.
*Note: The pro-rated amount is not a fixed amount and will vary every few hours.
The formula to calculate the value of the unused amount of the subscription is:
Amount paid for annual subscription previously (excluding tax paid previously) / 365 days [x (number of unused days)]
