It's okay if you only want to pay for one "Trial Class" and decide later, or if you want to pay for a few classes (less than 5) each time. Please be aware that only the "Pay in Full"(Pay Now button) option saves more and has a guaranteed refund policy if want to withdraw anytime. The "Pay in Full" option also guarantees a seat immediately which trial request will be assigned based on availability. The "Trial Class" or "Flexible" option incurs additional work for our team, so please be aware that you have to pay an extra $10 "Admin fee" for each transaction under this option.
