Confused about Speeding Ticket Given?

I was given a speeding ticket in california in violation of civ 22349 (b), in wet conditions. The speed limit was posted as 55 mph, I was travelling supposedly 80+ mph (written on ticket) but in reality I was going just about 78-80 (cruise control was enabled). Officer did not use a radar gun, just floored it until he caught up with me and used his lights. It was in the middle of night and i was just trying to get home. I am 19, this is my first ticket and first traffic violation, I know that the choice for speeding was wrong, I don't want to fight the ticket but I would like to lower it to about 79 or 78mph and maybe attend traffic school. The Modesto CHP pulled me over as well. What am I to expect from this ticket?
