Programming Interviews

So in my job search I've learned something important - I'm really really really bad at programming tests and interviews. Actually, I'm pretty decent at standard algorithms/data structures-related questions that come up on phone screens, but I'm awful when it comes down to ironing out the details and dealing with edge cases. Just now I horribly failed a take-home test and I feel like total shit right now.

I realize I need more practice, and I've heard from a lot of people that TopCoder's practice rooms are a great way to do it.

Here's the problem:

I find the problems, even the lower-point ones, to be WAY too fucking hard. Is there a similar place with problems that are easier, or at least less math-heavy?

I'm not confused about anything in that particular discussion, and my statement wasn't even about set theories at that point, it was about mathematical structures which can be encoded in finite definitions and enumerated. I would show you some papers that explain how this is done, if you were not a troll (judging from your post record).Fixed, I should sometime edit my posts before posting, not that I think you read any of them.
