I was in a computer class today, and a classmate of mine had made a blog about math and physics, the purpose of the blog is to teach people math and physics, he named it, "A blog for complete guides for math and physics.".

I'm troubled by his choice of prepositions,

I think it should be ""A blog

*of*complete guides

*to*math and physics."

What do you think?

What are the right ones to use?

Thank you!
