I agree with you that retaking the test is not to shape your scores, it is more to refine your opinions. All testing is weighted in a certain way, it depends on the amount of emphasis given to a certain field. IMO, agree/disagree vs. Strongly agree/disagree on this test has too big of a gap. When I modified just a few answers on this test, it switched me from slightly left to further left than Gandhi! Mind you, I didn't change my positions, just my conviction to my thoughts!
