I get tickets all the time. DO NOT go the class unless you NEED to. You only get three in your lifetime. Use them wisely. Do not get a lawyer. Way too expensive. It's only a speeding ticket. Select the court option. Show up in slacks and collared shirt. Please, please do not show up with sneakers, jeans or a t-shirt. Do not argue with the judge. Do not lie. And don't give some stupid defense like, "I don't speed."
The judge will most likely give you a non moving violation or seatbelt infraction and not give you any points. Also, if the cop doesn't show up, you win and you never have to say a word!!!
By the way, how old are you and how long have you had your license? That might also determine the judges mood.
