Ap state scholar award

I had a couple questions about the ap state scholar award:
When is it released?
How many tests usually does the person take to get this in Michigan?
Is this award only given to seniors?
Does the award only account to tests taken in 2015?
Thanks in advance

I got mine in mid-August (of 2011).

No idea.

No, anybody is eligible to get it. I think a few juniors grab it each year.

The award accounts for all exams taken in your AP career.
