I just checked out the test site at the College of Staten Island. It's building 5-S, the Nursing studies building.
There were no large lecture halls, just classrooms. However, It was very, very hot.
The A/C must have been set on "non-existent). There were only two classes being conducted. Both classrooms had left their doors open. I noticed several people in the classes looking uncomfortable.
I tried to check if this was the standard condition for this building and would there be an adjustment for the LSAT, but I wasn't able to get anywhere.
Thought I'd give you a head's up for whatever it's worth.
