Got a Speeding Ticket today

[CiVeK9]

Well....this morning on the way home from school between hwy 316 and riverside parkway one of those fuckers finally got me...i always see them pulling people left and right. it'd be nice if i knew a cop to drop it..but oh well..i need some suggestion on what i should do and if anyone knows the point system

Police

City of Lawrenceville Police (one of those black ford trucks got me)
I gotta goto the Municiple Court

Age

20 years Old (21 in sept)

Situation

Going about 78 with two other cars (decided to pick me of the 3)
Cop got me on laser going 78 in a 55

Solutions

I can't use NO-LO since you can use it once every 5 years..i used in 03'
I could plead guilty and let them know i was following the flow of traffic to get a reduced fine

Questions

How many points will go on my driving record? under 24mph 3points
How many points does a defensive driving certificate take off? 6 points
I think this law is just for 17 and under...but would i get my liscense suspended? its been a couple years since i got a ticket
no (doing 24 over under 18)
Does the defensive driving certificate ever expire? i got one from 2003 (not sure still)

any help or suggestions would be appreciated...also does anyone knwo the price? i called it in to see if they can tell me but they can't until it enteres the system..and the gwinett county site is down so i can't get a price
