Thanks everybody,
I was suspecting the ceiling issue was right. Oh well. It is a little frustrating.
So as I understand it right, it would be best to wait until he is 6-7 years of age. Or use the SB-5. I will have to research how it is available where we live.
I don't really know, how much would we be able to benefit from the Young scholar service. I am really just looking for guidance.
I am really not challenging him in any way, he does that plenty for him self. He has these urges "to know", so we go to the library and borrow around 40 books each week and I just read to him.
I will have to decide if we will continue next year, or send him to Public gifted kinder garden. Although he had testing with his knowledge into the 2nd grade as of now. We will see, where we end up at the end of the year. I am afraid, that he will be too bored at the school.
