I have a 12 and 10 year old. the 10 did Padi bubblemaker and the 12 did discover diving and went on a 30 ft dive.Both want to get certified but every instructor wants them to do the book work at home or online. They both watched the padi open water dvd and understand but the book is hard for them to follow. Are there any instructors that teach the kids the bookwork? im in pompano florida thanks Keith
