I am considering attending the Glenn Doman course on "How to Mulitply your Babies Intelligence', has anyone attended it before?

I have heard that it's really good but usually it only takes place in Philadelphia which is too far for us. But they are going to do one in Singapore so I am thinking of going to this one, there is also a discount offered if I can book before New Year, so would appreciate if anyone can give me some feedback as it's not cheap?
