K-12's biggest failure is low expectations. I was reading at three and doing simple algebra at six. If I could do these things, then so can every child.
My bro, you are an n of one. Anyone who learned algebra at 6 would know that something true for one case cannot be automatically extended to all cases - in fact, this single data point is almost less than worthless because it gives you the illusion of knowledge without any context.
Now that this thread is well dead, I can circle back and point out that you are asking me to boast that I am "gifted", and that is not going to happen. I'm not allowed to say, or even think, that I am different.
