Honestly, if you don't have 100% confidence in yourself and have to come on here to ask if it's too tough then Envoy may not be a good fit for you. It's not rocket science, but by no means is it easy. It's A LOT of info thrown at you very quickly and over a short period of time. I wouldn't say it's any more difficult than most other airline programs but it takes time, dedication, and lots of studying. If you struggle anytime during training whether it be in ground or sim, they will get you some extra help and work with you. If you were to get on the 145, which is more than likely what you'd get, the new AQP initial program moves pretty quickly and they will expect to to be able to regurgitate some knowledge and procedures early on.

Bottom line, it's tough but doable and they will bend over backwards to help you out. But if you're not totally confident in yourself or your abilities, or if you're a slow learner then it could eat your lunch.
