it's way too easy to score above threshold, I picked loads of really unautistic things, and barely any outright fully autistic options, and yet I scored above threshold
Your total score is: 93. This is above the threshold score of 65. You may have an autistic spectrum disorder and it may be worth consulting a qualified clinician.
Here is a detailed breakdown of your results:
Social relatedness : 36 (threshold 31)
Language : 6 (threshold 4)
Sensory/motor : 36 (threshold 16)
Circumscribed Interests : 15 (threshold 15)

See these quizes don't work because each question is worth the same amount of "points", so a question about a very basic and important aspect of autism like "Do you find it hard to read hidden signals" is considered equal in the scoring to "Do you walk on your toes".
A false positive doesn't prove that these "quizzes" don't work. RAADS-R in particular was developed as a diagnostic tool, and is not simply an online quiz.

Participant Grouping
The study population included 4 groups as follows: (a) subjects with a diagnosis of Autistic Disorder (n = 66), (b) subjects with a diagnosis of Asperger’s Disorder (n = 135), (c) subjects with no previous DSM-IV-TR diagnosis (n = 276), and (d) subjects with an axis I DSM-IV-TR diagnosis other than Autistic Disorder, Asperger’s Disorder, or PDD NOS (n = 302). Subjects in this group had the following diagnoses: Social Phobia, Schizophrenia, Major Depressive Disorder, Bipolar Disorder Type I and II, Obsessive Compulsive Disorder, Dysthymic Disorder, Generalized Anxiety Disorder, Post Traumatic Stress Disorder, Psychotic Disorder NOS, Anorexia Nervosa and Polysubstance Dependence. For some data analyses, the above groups were collapsed into two groups as follows: (a) Autism Spectrum Disorder (ASD) subjects (N = 201), and (b) all comparison subjects (N = 578). No participants from either group declined to participate.

Diagnostic Accuracy (Sensitivity and Specificity)
The total RAADS scores ranged from 44 to 227 in the ASD subjects and from 0 to 65 in the comparison groups. By ROC curve analysis, we determined that the best threshold for distinguishing between the two groups was a score of 65. Using this value, all 578 comparison subjects were correctly predicted with no “false positives” (specificity = 100%).
Six ASD subjects from three of the nine centers scored below the threshold (non-ASD predicted range). These “false negatives” yielded a sensitivity of 97% (see Table 2).
That is to say that out of 578 people with no diagnosis on the spectrum, none scored above 65. If it's that hard to score below 65, the outcome would have been different.
