How do I learn real analysis and not feel like an idiot in my real analysis class?

This.

Building your geometric intuitions is one of the best ways to gain a better understanding of any field of math, especially analysis or calc.

Unironically, read Rudin. If you find him too hard, Browder's Mathematical Analysis is a good option too.

Rudin is a meme.

Aside from Rudin's somewhat shitty approach that makes the textbook very unfriendly to noobs, I see no problems with it.

That's the thing is that it is extremely difficult for someone who's trying to learn some elementary real analysis for the first time. If OP is struggling with his first real analysis class, Rudin would be practically inaccessible.

Now, anon, that's an exaggeration. I remember it being pretty hard to read at first, but once you adapt to his "style", it becomes bearable. But the main reason his book is *the* textbook of Real Analysis is that it has the most relevant topics one needs to know in the course.

Just learn topology, then apply it to the real numbers.

If you took the spivack approach, Rudin becomes pretty easy.

This is graduate real analysis, which comes after topology and normal analysis aka advanced calculus in American lingo.

Our class system is basically: professor writes all the theorems and we must write the proofs ourselves. Then we go up in front of the class and present it, and he grills the shit out of us.

He's very thorough and tough, but that way we learn every detail and can't just skate by.
But I want to compete with the best guys in the class and not just scrape by. I like this and think it's fun but I just don't have enough hours in the day man.
