Speeding Ticket in NC?

I'm 17 and received my first speeding ticket. 62 in a 45mph zone. I was in a 55mph zone going 62, which I'll concede was speeding, when a cop turned the curve and passed me in the opposite lane. I saw his lights go on and figured he was pulling over the guy in front of him. He started to turn around so I knew he was after me. I was slowing down and entered a 45mph but by this time I was already slowing down to pull over. I passed a few front yards and was trying to find some place to pull over where I wasn't on someones lawn, I saw a place around the corner and started to pull over. Problem was the top of the ditch was muddy, it had been raining that day, and my car slid down the ditch. The cop turned the curve and kept going thinking I was trying to run from him and didn't notice my car slid down the mudbank. At this point, I could've stayed there and waited for him to leave, But NO! My dumbass climbs up the mudbank and waves him down, he was about to turn towards town. He saw me in his rear view and turned around. He immediately assumed I was trying to run from him and started screaming at me. I was still shaken up from almost crashing my car so I just let him yell, I was kind of frozen. I tried to explain my car slid down the bank when I pulled to the side of the road, he looked at the skid marks, called a tow truck and issued me a speeding ticket for going 62 in a 45, even though he clocked me in a 55, and gave me ANOTHER ticket for failure to maintain lane control because my car slid down the ditch when I was pulling over for him.

What do I do about this? I am trying to enlist in the navy and I need to get this ticket taken care of as soon as possible. I don't have money for a defensive driving class or court costs. Is there any way I can get this thrown out? It was my first ticket and I still have prayer for judgment but I haven't taken the defensive driving class. Is it absolutely required that I do? and if so will they waive any fees associated with the class?
