Self Diagnosis
Could you be on the Spectrum?
Short of seeing a psychiatric doctor, there's no way to be 100% sure that you have autism or Asperger's but there are some surprisingly accurate tests about.
The short answer is:
For kids, you should always seek a professional if you can.
For adults in continuing education, it's recomended that you see a professional.
For all other adults, it's usually not worth while.
This page explains why.
The RDOS Quiz is probably the most well known of the Asperger's Quiz sites. It's looking quite dated now and I don't know if it supports https (web security). Neverthless, provided that you don't put personally identifiable information there, it should be safe. It has the best diagnostic algorithm on web.
