IMHO, you don't need to know much theory to do testing. Programming is not a science, it's more of an art. Artisans don't need PhD's in Discrete Math to get their job done. Instead, they need passion, perseverance and tenacity. It's good that you want to learn about theory, but reading books is not enough... you have to code too.

He didn't ask to learn programming, he asked to learn CS. He isn't getting a PhD in discrete math, he is reading a discrete math book, which is a bare minimum for learning CS.

You are right and I stand corrected. I was somewhat puzzled that someone who has no technical background actually wanted to learn CS. That is unusual. Often people want to learn how to program and call it "CS", though CS has little to do with writing code. Thanks for correcting me.
