Sorry...I should have explaned better. I don't have time to do a the PADI referral dives in CA---I am in school and working fulltime. I was thinking about getting the manuals and trying to get some of the classwork done before I come to belize. I am going to Cancun and inland Belize for 4-5 days so I will have additional time for study while riding the buses. I will be on SP for 7 days over xmas. I know sometimes because of the weather, the PADI Open Water can take longer than 3-4 days and its performance based. I may even attend the classroom once on SP.

1. Will taking the tests, save me some time once on SP?
2. Even if you taken the tests can you still attend the classroom setting, to get a better understanding of the material?
