I've moved your question to the 3ds Max Beginners Area.
Well, I don't know of any school's in Saudi Arabia, but you might be able to find some online training. Or, if you're willing to relocate to California, the Gnomon school of visual arts is probably one of the best places to learn.
Other options would be:
1. Free tutorials, see here: http://www.cadtutor.net/forum/showth...x-Tutorials***
2. Training DVD's from company's like the Gnomon Workshop, Digital Tutors, Eat3D, 3D Total, etc.
3. Ask question's here in the forum. I'm always happy to help out Max users.
