Mel,
It concerns me that you don't understand that there is a whole slew of things that potential divers may need to know to maximize the return on their investment of time and money. It goes waaaaaaay beyond to the manner in which they speak to you. They can be super friendly, talk a good talk like a used car salesman, put you at ease, and yet your class is still a sh!tshow. My open water class was exactly that. "Oh you'll be fine", "it will be fun". They neglected to tell me how many things they'd skip. Remember that open water is a lot of material for a new diver to digest. The stance of "well, you should know as it was in the book" is while technically correct, but unrealistic as people don't retain every single thing in the materials.
The OP was rushed and appears to need some time to absorb material. A good instructor should be able to determine a student's comfort level, something that appears to not have occurred here (though I could be wrong, as I was not there).
I am amazed that both you guys want focus on a brand new OW student trying to have a detailed technical discussion with their prospective instructor, when in fact the original point was for the OP to go talk to their instructor -- or a new one -- and find out what the chemistry is between them. How can that possibly hurt the situation? Sure, you can be "sold a bill of goods" by a fast-talking salesman....but most instructors really do want to do a good job, it is just that some don't know how to do that with a student for whom it is not going well.Talking to the instructor was not the main point I made in my first reaction. Getting into a different kind of course was, one that doesn't have a commercially driven agency behind it. The fact that these courses are mostly offered through diving clubs and that you can talk to the instructor NOW THAT YOU KNOW YOU HAVE A PARTICULAR ISSUE is a bonus. My reaction was about what to do from this point onwards. Your point seems to be that talking to the instructor - even though you have no clue what to talk about - can prevent a situation as described.
But I am glad there's an instructor in the conversation who proves the first point I made in this thread so clearly.
