Hi.
I've been in your position, although it was 10 years ago now and things may have (hopefully!) changed.
The things I found that most difficult were having never met the person who was representing me (or representing the CPS, which ever it is), I was given no opportunity to speak to him before hand. Also, I was given no preparation or support at court. I had no idea what sort of questions would be asked, where I was supposed to sit, etc. So it might be worth seeing if you can visit the court before hand and get some idea of what your prosecutor is going to ask you. I would've found that useful.
The defence questions weren't to bad. They definitely tried to trip me up (I would ask to reread your statement before hand too). They mainly let me answer simple questions, until he got to a specific point - he had said a certain word to me, and after he asked me to confirm that part of my status he hit me with "my client has a speech
Impediment and couldn't possible have said that to you. What else are you lying about?"
It would've been useful to have been prepared on how to answer those questions.
I was also unprepared for the fact that people could sit in court and watch. People he knew, family and work friends. Also, I didn't realise, they they could call people to discuss my character and previous behaviours. Hopefully they no longer do this, I don't know.
I would suggest keeping your answers short and to the point.
"Do you think your behaviour led him on?"
"I don't think so.."
"Not really"
"I didn't mean too"
All give him the chance to carry on badgering you. Stick to 'No' or 'Yes'
Back then, there was no segregation at break times. I had to eat lunch with him at the next table. Hopefully that's changed too.
I found it easier to pretend I was in a TV show, just playing a part. I tried to detach from it as much as possible.
I don't want to sugar coat anything as being unprepared was the worst part of it for me.
This was a Crown Court, maybe each one differs.
