Math Academy does not charge your card for the first 30 days. If you find it's not a good fit for then you can cancel within this period and you won't be charged. 30 days hopefully gives you enough time to determine whether it's a good fit or not.
My colleague informs me that, contrary to my previous message, you get charged immediately, but you get an automatic refund if you cancel within 30 days.
