I don't think anyone could succeed in a coding test without rehearsing before taking it, just like any kind of live performance.

Programming languages are powerful things with which you can do a lot of very different things and tackle very different issues. Sometimes it's database querying, sometimes complex data structures, sometimes parallelism, genericity, business data modeling, etc. etc.

There should be a list of "warm up" exercises somewhere to help people prepare for general tests and make sure they've touched at least every subject once before going live.
