Affinity for sciences

Hay guys, first time here!
Tell me, how talented do you feel you are in maths? Do you often fuck up tasks because of the lack of practice?

As for me, when I was a kid, I really hated paying attention in school, and never saw any purpose in practicing shit, so I really sucked at maths and physics. Now I'm studying to be a mechanical engineer at a university, so things have changed quite a bit.

I don't own a copy of the book, but judging by the ToC on Amazon's "look inside this book", I covered that material and a bit more in an introductory real analysis class that I took my freshman year. (The text was Rudin, Principles of Mathematical Analysis. We covered all but the last chapter.)
