If your reason for diving is marine and aquatic life observation, do that instead of spending a lot of time and energy on the GUE course. There is a lot to see without entering caves and shipwrecks concerning marine or aquatic life, so go for that. My understanding of GUE is that they are grooming divers for technical diving, deep diving, wreck diving and cave diving. But rather than all that, simply go diving.
