A bit of work, but thought I would share anyway, more useful if you actually want to use Mathspace Plus.
My understanding is,
1. open a Westpac Choice account for the studen who will use Mathspace Plus.
2. subscribe to Mathspace Plus for $10 per week. there maybe a free trial period.
3. link the two accounts
4. successfully complete weekly maths task to get $10 reimbursed
5. All new Choice customers will get a $20 reward from Westpac
6. repeat step 4 still you receive the $20 reward and can cancel the subscription.
T&C
*The $10 reward for successful completion of weekly maths tasks is not available during a user’s free trial period.
**Offer available to customers who open an individual Westpac Choice account and who have not held an individual Choice account in the last 12 months prior to account opening. Customers must link their eligible Westpac Choice account to their Mathspace Plus account within 31 days of opening the bank account. Customers’ identity must first be verified by the bank to receive this offer.
