Hello Tushar,
Don't bother much about the test center. Any test center folks shower hospitality to the fullest. The desk, the chair, everything will be comfortable. Because it is MI and it's getting colder as the fall season has started, just keep warm inside the test center too. I faced this issue at my test center in the middle of verbal. Keep 5 mins safe in quant possibly incase your pens and notepad are bad and not very useful. They gave me two useless pens at my center that almost stopped writing properly after 10 questions each and thereafter, I lost my cool by getting aggravated at every question further.
All the very best, no trivial stuff must disturb you and your preparation all this while, keep in mind and attempt your real deal with the best of confidence!!!!
