Keep in mind that NSS is, by nature, based on a lot of things that are out of your hands. One MIF 3 in a field of 4's doesn't hold you back. If you happen to be contemporary with and behind a boatload of rockstars, then them's the breaks, but if you're among a boatload of average students, you're gonna be just fine. Either way, you still have plenty of opportunity to get your wings.
Do your absolute best, make notes for yourself on your own performance, at least in your head, and try to engage instructors based on those observations, rather than on some arbitrary grade system that all squadrons consistently have to work to maintain standardization in its use. Lately, it's seemed that many select what they want out of primary, and grades aren't usually a hindrance. As long as you're on track and not on SMS, you should endeavour to learn, as you have, and enjoy as much of these flights as possible, because you have enough to worry about without making pure grades your priority. Being the best aviator you can be is the goal, not being #1 in the class. If that happens, good for you, but beware the quicksand of misplaced priorities.
That's at least my philosophy.
