There is at least a period of time that she has at Beacon. After the initiation, we time-jump to Jaune's fight a Glynda mentions that is has been weeks. This could imply that a month has past, or maybe even two. We also don't know how much time passed between the events of the Black Trailer and episode one. Blake obviously has no knowledge of the White Fang's business deal with Roman so it could have been a year or more. Plus Weiss kind of cuts her off before she can go into more detail, so maybe she had more to say.

This all adds up to her not lying about being younger when she quit.
