Don't bother binding. Turning the page takes the same amount of time bound or unbound and if you have made it this far in life you shouldn't have an issue with this on test day just because you didn't bind your PTs.

I took the June 2015 test here. It was quiet and proctors were strict with timing. My hall used the smaller pull-out style of desks but you should have the seat next to you free so, I thought space-wise it worked out well. Be prepared for a long day!
