Doctors referral for an autism assessment advice?

I have my doctors appointment tomorrow which is to get an assessment arranged for Autism.

(If you remember my post from a few days ago, you’ll know the backstory)  

What would would the questions my GP would be likely to ask me? Below is what I’ll be mentioning to my GP any advice is appreciated  

Heres a recap:

- I’ve completed a couple questionnaires on this site and on others where the results indicated that I have autistic traits. 

- I have typed up a bunch of traits and odd habits I’ve noticed on and have them stored on my notepad. 

- When I was younger, I was never tested for autism but in school I wouldn’t speak to anyone. I was referred to a Cognitive Behavioural Therapy charity where I just started speaking to them completely fine. (That was the end of that)
