Dr. Math offers several convenient payment methods including credit card, Venmo, check, or cash.
The most popular option, by far, has been the monthly credit card plan where payments are spread over 10 months, August through June. The total amount for the year is divided into ten equal payments due on the first of each month. Families make the first month's payment using an online payment processor, and all subsequent payments are made automatically using the same credit card. At the end of the year, any adjustments are made, depending on the number of sessions actually used.
