If you wish to withdraw completely and cannot reschedule, $100 of your deposit will be refunded (to cover the cost of the study materials sent when you registered) if you notify Cal-Earth two weeks prior to the start of the workshop. Any cancellations within two weeks of the workshop will not be refunded. The full amount of your deposit will only be returned if for some reason you are not accepted to the program.
