OK then, this makes more sense. Jumping and nipping at you at 3 months from a BC cross is pretty normal. It is NOT aggressive. This is her attempt to get you to interact.
Do not shout at her or punish her. It will only get her more excited and out of control. Really... you have probably noticed that.
Walk away, crate her, put a baby gate between you and her, have her on a leash and clip the leash to the table so you can walk away... all ways you can remove yourself as a "play object" and stop the fun. Stay very calm and do not be at all upset with her when you do these things. MOve like molasses.
It is imperative that you stay VERY, VERY CALM with her at all times. Much of this sort of behavior is unknowingly elicited by the humans who get the puppy too excited when playing with her.
Notice what precedes this sort of behavior. Has anyone been speaking in a high pitched excited voice? Has anyone been playing with her actively? What ever comes before this, try to change.
When you play with her, be very calm with your voice and hands. Move slowly. Make the TOY you are holding more interesting than you, or your hands or body. Never ever invite her to wrestle with you. Always have a plush toy or ball or something she likes in your hand and keep her focused on that.
