Lisa,
Diedra is right, pray...you have to have a peace about the situation and know that if it is God this will not be a missed opporitunity...but a heads up that you are getting ready to be used ...It sounds like you have a gift that is anointed and its beginning to shine through...however...I believe your book work is your first priority...and if you know already that this will be a distraction then its not time...Diedra gave you some good tools for preparation...I had to ask God to hide me from things that would easily distract me from getting my degree. If leading a group at this time will get in the way of your education then it is not time.
