I’m not sure why you were paired with a CRT, you’re supposed to have a teacher who works there because they’ll end up evaluating you and also mentoring you as well.
The thing about CRT is that kids/students will act differently to a CRT, especially one they’ve not had before as the students will try and push the boundaries to see how far they can go.
Anyway I’m a little bit sad that you hadn’t gotten the proper set up to experience it properly and you only have a short time to make a decision.
This might not be too helpful but you could reach out to your uni for advice perhaps.
I’m not really sure of the right channels to go through but I can ask some friends tomorrow if you’d like.
