Congratulations on getting in the class.... (what term? I will meet you there if it is summer)
From the talks that I had with a couple GF's from PGE it is important. They said that a large problem that they have nowadays is the driving record of people. They told me not to worry to much about anything over three years.
The only tickets I have ever gotten are speeding tickets and I may or may not have had the last one inside the three year mark (have given thought on asking for my records at the DMV)
I would say be prepared for a question about it for sure .... (is this the school interviewing or employers after the school?)
