Can I add additional Math Passes after my original purchase?

Of course! You can purchase as many Math Passes as needed at anytime. 

Math Passes purchased in the same transaction will receive the following multi-Math Pass discount:

• Math Pass 1 - $79
• Math Pass 2 - $59
• Math Pass 3+ - $29/each

If an additional Math Pass is purchased after the original transaction, it will be assigned a different expiration date and will cost $79.
