The class is easy as fuck and they actually give you the answers before you even take the test, plus you might get to watch one of those cool "Don't do like Jimmy did and D-n-D" movies they sometimes show (depends on the cirriculum of the course per year, I saw one that was pretty graphic... blood and guts = sweet...).

Speedo calibrations are overkill and don't always give you a free walk, plus they sometimes cost more than the class/fines you might be trying to avoid. I had a friend get himself in worse shape that way with the courts when he got busted for speeding over 20mph. He got calibrated and found out he was was off by about 15mph or so and took that evidence to try and beat the rap on the RD. He got hammered with the fines WITH additional money tacked on for Improper Equipment (off speedo), the cost of the calibration (idiot didn't fix the problem, merely got the calibration = stupid), AND the reckless. The insurance co. ate his ass alive. Of course, there was a lot more "Improper Equipment" on his car than just an offset calibration, believe me...
