one very important thing about doing GD and SM .... it really does need a pro parent .....
If you mention educationally better .... meaning acedermically .... do GD.
Don't belief totally in schools result nobody publishes failure rates ...... they only show off their stars ..... results should be seen in its whole totality ...... .... there should be at least 70-90% success rates for students in the IAHP program ..... to be classified as success .... unfortunately talents are ..... a subjective thing and each child has differing talents ....
For some results .... of people doing it at home try this link .... i posted some results .... and so did some kind parents .... but am also looking for more info on how such babies have become when they are adults ...... do they still retain their talents and how much effort is put into it throuh out their life .....
