Hi Debbie
I moved your post to one of its own as it can become confusing to have different topics within one thread.
I can't find a time suggestion on the IAS official website but I would always try and arrive at least ten minutes early, so you have a few minutes to gather yourselves before the assessment. (Of course sometimes the assessments are running late). A lot of people don't turn up too early because of the stress of waiting in a strange environment.
