I'm starting Piney Point Apprentice program in 3 weeks help!

Hello All,
I’m new to this site and just wanted to know more information about Seafarer ’ s apprentice program. I’m starting in 18 days and would like to know what should I expect? Who else is starting with me? What should I avoid doing? How simple are the classes? Will I be able to leave and go home after each phase? Etc. TIA
