Reply #32: but isn't that valid to some point?

[Clovis Sangrail]

yes, a test on the same subject can be made more or less difficult ... but in most cases it seems there should be some commonality that can be reached an is impartial.

ie: arithmetic
how can a math test on a subject a student is supposed know be skewed?
(aside from word problems)
if they are supposed to know multiplication of whole numbers it really shouldn't matter *what whole numbers you ask them to multiply.
