None of the above.
A test with its own scale. Easier than Orgo and biochem final, but under more strict time constraint.
I guess the fact that it is invloved with many different subjects and skills makes it look harder. It seems as you study for one subject, the other subjects are compromised and as you switch to other subjects you feel the other ones are neglected and the vicous circle continues untill you get tired and go take the test.
If you want to get a very close feel about it, do one of the sample tests and you will get a feel for it.
