Help..My husband failed the NCLEX twice

Hey everyone..my husband graduated nursing school in May of this year and he just failed the NCLEX for a second time. I'm surprised he failed because I know he is an intelligent man and it seemed like he did well in school. I do feel like he has studied a little more now than the first time. He is clearly upset but don't know what to really say or do to help him. I am an RN and have been working for three years and offered my help to him for study and he declined..I told him how I studied for boards. I know he did the Saunders practice questions but obviously that hasn't been working for him. This has been very hard and stressful on our new family and I know his manager has been holding a nursing job for him waiting on him to pass but worried about losing that potential position as he is working as a tech now. Any study tips or any kind of advice in this situation is appreciated.
Have him do a Kaplan course, he knows the material but needs help with picking the right choice I believe.Sent from my iPhone using allnurses.com

He's probably over analyzing the question. So many second guess themselves or read too much into the questions. That darn NCLEX can be tricky especially when you are already stressed.
