You can take your own notes to the assessment the only thing I would say is that if you have to refer to them then you should explain why you are doing so to the assessor.
I would be very surprised if you have the time to take any notes during the interview!
You can refuse any activity that would cause you unreasonable physical or mental distress, again, make sure you explain why you are doing so.
