Got there at 6am and there were already about 80 people ahead of us.
At 6:15 they started handing out tickets. At 7:30 we had ours.
Went inside to sit down and at 7:45 our number came up. Handed over copies of the I-765 and I-485 receipt notices (it speeds up things if they do not have to make the copies) and newly filled out I-765s (they want them).
On the 90th day, I make an appointment. The earliest day on infopass is 5 days later on Friday, so I make that appointment, and print out the sheet confirmation with the barcode.

On Friday

I went to the line at 10:00am for my 10:30 appointment. The guy at the door says you can't come in yet, come back 15 minutes later. That means even if you come really early before your appointment it is pointless. It is best to come 15 min before.
