Currently, you cannot change credit card details for Maths Online. You will need to cancel your current subscription and re-subscribe. You will still have access to your current subscription from the date of your last payment to the date that your next payment would have gone through. Please make sure to cancel your subscription and start again. Don’t worry your progress will not be lost.
This is something that is out of our control to change due to the security controls put in place by our payment gateway provider. We fully support these measures as card security is paramount to Advantage Learn.
