Interview and Chance of Acceptance?

I just registered to do an interview with U of R in November, I was wondering if anyone had any tips to make a good impression? What should I talk about, what should I avoid, things like that. This is one of my top choices.

Also hoping you could estimate the chances of me getting accepted.

Stats:

GPA unweighted 95.510
SAT superscore 1380 (of 1600) / 2010 (of 2400)
ACT no score, will take next month
All four APs I’ve taken, I’ve gotten either a 4 or 5 and I’m taking two more this year
I think my recommendation letters will be pretty solid

Clubs:

Drama Club (Secretary)
Peer Leaders (may be an officer this year, it hasn’t been decided yet)
National Honor Society
Best Buddies
Environmental Outreach
Mathletes
Jazz Band (in 9th grade)
Softball (in 9th grade)
Art club (in 9th grade)

Volunteer:

Counselor in Bible Camp (70 hours)
Garden Club
Middle School Drama Club

Jobs:

Local Restaurant (1 year)
McDonalds (1 year)

Tips for the interview are mostly to be yourself and don’t spout your resume, which they can read. Talk about what you’re interested in and why and why this school.

I have no idea how to evaluate chances, particularly for a school which looks more deeply at applications than some.
