Hmm, they had a similar timeframe in FL, you couldn't "elect" to take the school in place of points twice in a certain time period. However (at least in the past) you could go to court to fight your ticket and when they had the pre hearing the Judge offers pleabargains to weed out the weak cases. At that time they usually offer driving school in place of points and it did not count as an elected time.
Last time I went to court they offered me $100 no points no fine for a 9MPH over the limit speeding ticket I had no real chance of beating. I was all over that. That was more than 5yrs ago, so, courts may have caught on to this workaround, but, I suspect not.
