do I need to do anything prior of taking my written test or can I walk to the line?

Be prepared to wait in a long, long line for a long time. You can just go there without appointment.

Just have all your 6 points. Yes you can do it there also.

U need to study a lot so you dont fail the test, and so u can be a great driver. not like all the morons that are driving out there! Good luck!
