What?? That’s BS. It is scored on a scale of 200-800. Look up raw score conversions. Depending on which subject test you’re talking about, you get a fraction of a point taken off for every wrong answer, as opposed to 0 points taken off or given. The reasoning test doesn’t deduct for wrong answers because it’s based on critical skills and how to do your best interpreting the test, while the subject tests are based on knowledge that you should have.
