I'm currently in IFS and so far haven't enjoyed it a whole lot. However, whether I like it or not doesn't deter me from giving 100% at everything I do. I'll give that effort regardless of my attitude or personal opinion of the validity of the program for SNFO's. However, I have a little bit of a problem with being told that my whole naval career in aviation may ride on a solo check-ride given by a civilian instructor.
Don't take this the wrong way, I'm not complaining. I'm glad to have the opportunity on the navy's dime but it's a military screening process not run by military personnel. Maybe some were but a lot were not and having several different companies do the training means you get huge inconsistencies in the screening process.
Which flight are you on? The check rides arent that bad. I suppose if you're having a real hard time keeping your heading and altitudes constant it might be difficult, but the instructors told me that the check rides are also to evaluate how your instructors have been teaching you. I was sort of worried about mine too before I did them, but by the time you get there its really a piece of cake as long as you paid attention to everything and studied things that you were weak on.
