Isn't rapid used in the phrase rapid acceleration, used to describe acceleration. Acceleration means faster. So rapid acceleration means really, really fast.

Now, maybe I am too old and rapid is an old fashioned word and I should have used radical. Is anyone using uber?

So acceleration means faster. I shall be the one, THE ONE, to define what we mean here --- so 1-2 years. Does that work people?

Rapid acceleration means 3-5 years. And Radical acceleration means 6+ years ahead of schedule.

Mark, are you going to post these definitions somewhere so we don't anymore misunderstandings here?

I think any gifted kid can do acceleration. More highly gifted kids may need acceleration and rapid-radical acceleration in the math. How much more than 2-3 years ahead needs to be in language and literature, I do not know.

I know there are a lot of Shakespeare plays to read in high school. ---just joking.
