I do on occasion disagree with myself, it has been known.
The reason tests (any test) are the way they are is because they cannot (yet) monitor your behaviour continuously. They know you will behave differently while being tested. To ask if you'd pass while being watched continuously by an examiner is to completely misunderstand the whole shebang.
