The Beat Referral Program
All you have to do is have your name listed on the "how did you hear about us" section of the registration form. Every student who lists your name and takes class for at least 3 months will get you a $20 credit.
If a student lists more than one name on the section, the $20 will be split evenly between the listed names. Siblings count individually, so a family with two kids will get you a $40 credit. Tell your friends!
