Normally I recommend waiting for the course before riding but it sounds to me that you have a lot of fear. It also sounds like your hubbie is doing a great job and is very patient with you so I would say stick at it. If you go to the class with a lot of fear you may end up bailing out. The trick is to be able to relax and sometimes that just takes practice. But the most important persons point of view is your own. If you would be more comfortable waiting for the class then just do that. Best of luck with whatever you choose.
