Can you please find out which airline this was and remind me never to fly on them. If their SEP trainers are saying that then I would hate to think what you are taught for a cabin fire... or better yet a decompression!
Recently we ahd an intake where one guy couldnt swim so they allowed him to get some swimming lessons and once he got a certificate he was invited for the next intake. Luckily that was just a couple of months later, but if you are required to wait, just more time to learn!
Go for it!
