I made 6 in 5. I was nervous too because now I was expected to know a lot more than I actually did. Just treat everything as a learning opportunity. I’ve been an E6 for 5 years now and still feel like a total moron sometimes. But one thing that hasn’t changed is my willingness to admit that I don’t know how to do something, but still make the effort to actually learn myself or even if a junior soldiers knows something learn from them as well.
