Not a nightmare...
I had never had to go to traffic school before and was a bit nervous, but no need to worry. The people I talked to on the phone were very nice and helpful. The class was quite long, but very informative and concise. I was able to start and stop when needed so was able to do the class over a few days time. I learned some things I had not known and never considered. It has made a difference in my driving. All-in-all, it was a good experience.
