>> I suspect it had just as much to do with who was grading the tests.
Yeah, that’s the real issue. There are enough places where a grader with a mind to mess with the test-taker could do so, easily.
Yup. You didn’t draw a line around that number, you drew a circle.
You didn’t draw a cross above that letter, you drew an x.
Its actually a pretty good basic test if it’s fairly graded.
