Reviewing test score?

[IronBruin]

Usually whenever I leave a test I know within a few percentage points how I did on the test. Leaving this particular test I thought I nailed it, but I got the scores back today and they are REALLY low. They say the "average" T-score is 50 and my score was well below that. I am actually shocked. I guess my question is, is there any way to review the score, my answers, or ask for a re-grade? It's not the end of the world but I honestly think the score is wrong.
