To quote myself on the matter. lol Basically based upon how they do at the Citadel this usually means Second or Third Class since to be put into First Class right out of graduation is a very rare thing indeed.

Mostly they will be a smattering of Third Class and Second Class. For example Setzer is second class. Use your better judgement to decide where they place on that spectrum. Nobody 'should' be First Class but if you make want to go for it and make a CS that will blow my socks off then sure go for it! I'll just judge it much harsher than the rest. 

In the end their class don't really matter though due to the nature of the plot they never really end up going to fight in the front lines anyway. They are too busy trying to save the world and stuff to worry about things like politics.
