How to get started with Scheme

I am just about to join an IT company as a fresher .The company requires basic knowledge in Scheme programming language.They use DrScheme.

They provided us with a link to some MIT online material. But the theory there is a little obscure , and i need to know it from the scratch.

Can you suggest some books for this purpose?

I sincerely apologize for the Heading i provided, it was a little childish.

Thanks, Ulf for making it more comprehensible.

I also have a question, is this book "Structure and Interpretation of Computer Programs" mentioned in the given link about Scheme programming?
I went to amazon, but couldn't gather that information.

Yes that book is about scheme and lisp in fact. I used that book back in uni for the "Intro to CS" aka Scheme programming class. You will learn from it recursion vs iteration stuff. Great book for scheme.

Thank you Tsang
