The right and best websites for the AQ-50, EQ, and RAAD-R tests

Hello everybody,

I would like to prepare the AQ-50, EQ, and RAAD-R tests and send them to my GP with a letter as an evidence so I can get an assessment for a formal Autism Spectrum Condition.

I have searched for these tests but many websites come up.

What are the best and the right websites where to complete the tests and print out the results, so I can add them to my letter?

Could you let me know, please?

Thank you so much for helping me!
