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?

If that wasn't clear, I'll write it in a language you can understand:
If putting something into words is literally impossible, why bother talking about it?

I'm done responding to you, you're boring and you try to compensate for your stupidity by acting smug and trying to insult people.
