Diving courses are performance-based. Occasionally, additional days or training dives are required for students to meet the course certification standards. You pay for the training, but you have to earn the certification. I endeavor to allocate contingency days on most course schedules to anticipate extra remedial training being necessary. I strongly recommend that students do the same, and reserve 1-2 surplus days after the scheduled end of training and prior to departure. If those days are not needed, you might opt to conduct further training dives anyway, to enjoy some post-course fun dives or to simply relax, dry out and enjoy the non-diving attractions of the area. I do not charge additional tuition fees for extra remedial training days, within reason and provided the student has (1) arrived for training with the prerequisite skillset, and (2) abided with the Student Learning Agreement (see below) throughout the duration of the course.
