<p>No. The test covers such a wide range that not everything is on every test. Right now if one person knows everything but Topic A, and another person knows everything but Topic B, both will get 800, regardless of the test they get. That is a fair and accurate way of deciding their score. If 1 wrong = 790, then their grades depend on the luck of what is on the test. If Topic A is on the test, but Topic B isn’t, one of them is screwed just because they got the wrong test. That would be unfair and arbitrary.</p>
