trust me his test are hard, their are always two answers that are right but you have to pic the best one.
Could you please provide an example of these tests?
Because if this is really the case, then it's a very silly way to examine students' knowledge.
I would even say that it's fundamentally flawed, and contrary to the purpose and the sense of science itself.
How is it possible to give
two correct answers to any scientific question? If you can do that, then either they are both wrong, or they are equivalent. Ask a mathematician if you don't believe me.
We are not dealing with
opinions, but with facts, observations, measurements... the only bit where there is room for opinions is when you still don't know something, and therefore you make predictions. But no prediction has any validity until it undergoes experiment.
Is your prof. expecting that you experimentally check the answers while doing the test?
So I totally agree with people who don't like this sort of tests for organic chemistry, and I add that this looks much like a trick your prof. cunningly devised to work less and choose who he wants to favour.
