This test looks like it has basically the same questions I've seen in other Autism Tests. I've been professionally diagnosed twice but I have to say I like taking these on-line tests. A lot if not all, of the questions in the Newsweek test is covered in the DSM-5. Also this test was created by reputable sources, I notice. So far I like this one better than any of them because the severity is given which is low, average, above average, very high and maximum. I got a 37 on mine.
