I had given a poly test recently. Inspite of being 100% truthful, I failed to clear the test. I was ready for the test because, I thought it's an opportunity for me to prove my innocence. Also I was ignorent about the facts of this test. Only after I was told that I didn't clear the test, I was curious & searched on the web for more details. I repend that I should have done a little bit of research on it before appearing for the test. As per my experience it's 100% wrong & it should be abolished.
