what to expect in court?

Sorry I know this has nothing to do with this app but I'm scared. I have to go to court for a speeding ticket, I was going 66 in a 25 and trust me I know that's bad. This is my first time getting a ticket and going to court so I don't know what to expect. I'm just really scared, I know to dress nice and to arrive early. Will they ask a lot of questions? Should I say your honour when I answer to the judge? I'm really freaking out I'm having my dad come too cuz I'm that scared and  I'm 18. Any tips would be great!
