Hey Priscilla.
You are saying that you have exams at that period.
I know, everyone has exams then, and now the tourdate is known, you know that it is in June.
But hey, it happened to me 2 times that I went to a show with an exam coming the day after. So do me a favour, and just don't bother about it and go to the concert. Just make sure that the exam you have the day after is revised early before. It isn't such a problem, because when you are studying that particular thing you will be thinking: when I'm doing this exam, I will already have had the most wonderful evening of the year.
Believe me, I've done so and it worked! And Bon Jovi is the ideal break when you have exams!
