Depends on which academy you are attending. USAF Academy? Westpoint?
I would expect it to show on your DEC LES statement. Most likely, it's 0-1. But that's just a guess because it is perfectly possible for a cadet to start the academy as an 0-2 or higher, depending on their background experience and what course of study is being pursued.
If anything, the local paymaster can definitely answer this question for you.
