Its not a scam. I went to the Oman embassy and the person incharge confirmed me that this school exists. The person calling me is Yahya Farsi the incharge of the school. Its a good school working since 1994. They dont have any website because its not an omani culture people dont usually make websites there unless they have a big business running. The person confirmed me that he has personally met Yahya and he knows him well. His relatives children study there in that school. So he being the representative of oman said that i should go for it, there is nothing fake in it.
