How well do you think test/exam scores predict a person's future success with a particular subject?

Test and exams seem (I'm using the word "seem" very intentionally) to be a way to measure what someone learned in the past (after having taken a course for example).
But can tests really predict what's important? That is, future successful action!


Closing Statement from Doug Edwards

Thanks everyone for your contribution to this question. If I had to summarize: you think that tests alone (some intelligence tests excluded) are not enough to make a prediction, but are mainly useful to see a student's progress (or lack of it). Your thoughtful answers were very helpful to me.

    Mar 1 2014: The GMA is a predictive exam, designed specifically to predict future ability and seems to have some success in doing so. I'm mainly talking about exams given in schools (I should have been more specific) for people learning a specific subject. I'm doubtful that very many of those exams are designed with the predictive rigor that the GMA was designed with. And if not, why give them?
