Ask HN: Timed programming tests

I want to gauge my thinking speed as a programmer, so I'm looking for sites that have timed programming tests, and that show how your response compares with others. I'm rusty with algorithms, so I'm looking for tests that require more basic techniques, such as for loops. I know of Codility, but, sadly, they only have two tests available. Are there others that meet these criteria? TopCoder, spoj, and others don't fit the bill.
